Single player games in your Steam library that you're not able to finish

Max Payne 2, Devil May Cry 4.
Couldn't finish them because of technical difficulties

Skyrim, gotten boring after some point
Alan wake - way too repetitive, great story and stupid gameplay

Life Of Pixel - It's a pretty nice platform game but I don't think I'll finish it. As a matter of fact I already finished it (got the congrats screen) but not all levels (and not all systems) so I don't count it as finished. It gets pretty hard on 16 bit systems levels. I liked it though, it's educational and each world has graphics of a different system (from the oldest ones to the newest ones) which is a really cool thing. So if you're into retro platform games then go for it.

KickBeat: Steam Edition - Nice mix of rhythm and fighting game. You stand in the circle and have to press corresponding buttons when enemies approach you. I don't know if I'll finish the campaigns though as this is the kind of game you play every few hours for a few minutes to relax. But it's nice it even has a campaign (two actually). If you're into such games give it a go and you'll probably like it.

Squishy The Suicidal Pig - Pretty nice puzzle platformer in which your goal is to die as many times as possible. But it's not as easy as it sounds, especially that you'll have to solve puzzles in every level. I'm in no mood for so much puzzles now though so I'm gonna leave this one.

Amnesia - Worst "horror" game ever, also gave me a window on why artsy pretentious pricks have to be artsy pretentious pricks...because their most loved games so clearly suck, and most admit it after enough nudging.

Alan Wake - Great atmosphere, moronic combat, and the worst "good guy" character in years. Honestly, if the darkness had gobbled up mister author, the game woulda been better off played through with an invisible lead. Finished the original game, skipped the DLC and wiki'd the story in that...and skipped American Nightmare, since it's just more of the same, with the same dick.

Watch Doge : I regret this purchase.

Fallout NV DLCs : First one I played was Dead Money and that pretty much killed it for me (finished the main game several times though).

Skyrim : Cough cough, I've played rather far multiple times, nearly finished once, buttttt you know... yeah.

Rome Total War : After about 8 hours I was just done.

Borderlands 1 & 2 : Super boring. Sorry.

From Dust : You know, I'm not sure why I never did, I just stopped playing it one day and never went back.

It's early days, but I'm not sure I'll finish the Witcher. Seems a bit eh so far. Also, surprisingly, haven't gotten into the Batman games. 8 hours into Asylum GOTY and 1 hr into City GOTY so far. Both sets of games look good, but just haven't quite clicked with me. Darksiders 2 the same thing. Farcry 3 seems alright, but it's on pause for the moment. I'm starting to think that maybe I just don't finish many games :S

Also definitely won't finish Lord of the Rings: War in the North - but that's due to bugs preventing me from doing so.

Heh ... I have ... well ... a lot ... if you look at my library ... only about a tenth of them I've actually beaten.

Hippocampal: The White Sofa - One of the "artsy" type of games. It's terrible, the worst of the "walking" kind I've played. For starters you can't change any settings whatsoever so you're stuck with a small resolution even though the game uses Unreal Engine so there are plenty of options available. Only the devs wouldn't let you have it. Anyway, moving on, controlling the character is terrible, you float as an astronaut and it's very slow and tideous and you constantly bump into things. Also, the first level I've seen (couldn't bear the game any longer) is a city but it's so awkward and ugly it can't even be expressed with words. This creation looks like a broken screen saver from the 90's. Omit, omit, omit.

Out of my small collection..and I am including games that were sold to me as single-player, but are in truth and outside of advertising, really multi-player games...

Space Trader/SpaceHack - Free games, ugly, can't get a feel for them.
Terraria - Game with no real point to it, packaged as single-player, in truth it's a multiplayer game. Multiplayer community is a bunch of choademuffins.
Hammerwatch - Boring, horrible graphics and this from a guy who grew up on an NES...

Crysis 2. It was great looking, but extremely boring. Uninstalled about halfway through.

Goat

Strike Suit Zero(not Director's Cut in witch,finale is easier)and Hotline Miami. They are cool,but it takes many hours to complete the late game missions.

Batman Arkham Asylum because it started laggingg like hell, in game massive fps drop unplayable :/

The Escapist - It's a platform game but it's really boring and controls are terrible. Levels are small and the game is just very poor in general. I can't imagine anyone enjoying this.

Rush Bros - It's not a bad game but very average. Rather boring and uninteresting. Platforming is mediocre, music is okay but there's no story and you just complete levels one by one and it's all without any connection. Might be fun for co-op, I don't know because I don't play such modes.

Not The Robots - It's a rogue-like stealth furniture eating simulator. If you like such genres then you'll probably like it as the game's pretty nice. I'm not in the mood for it at the moment though, I may come back to it some other time.

Ilamentia - First person platforming game with psychodelic looks. It's boring, you just enter level after level and you have to figure out what to do (mostly just jump around and shoot stuff). It's not terrible but it's nothing special. Also it's very annoying that you can't change the resolution so graphics don't stand out either and you can see pixels everywhere.

Meltdown - Pretty nice game but it has a few major flaws that threw me off after playing for about an hour. First of all every level looks the same. It has "random level generator" like in rogue-like games but still the more you play the more you see a pattern, there's like 20 "parts" of a level and they're just switched places from level to level and that's it. Also, if you want to beat the game you have to grind a lot. So let's see, repeating basically the same levels just to get better equipment to see even more same looking levels just like before. Hmmm. Also, there's basically no plot. Intro is very generic, it's like 30 seconds long so I expect the ending will be like that too. It's not worth it. If you like grinding and don't mind playing basically the same level over and over again then go for it. Because the actual gameplay and the mechanics are pretty good.

Gauge - Wow, this is boring. I lasted 2 minutes. You basically have to press/hold space and make sure the growing bar won't go to far. I don't get where's fun in that lol.

Fowl Space - It's a platform game but not a good one. First of all the game doesn't run smooth, I suspect 30 FPS lock. Controlling the character is bad, feels very floaty. Also, the game is very boring, you just jump around and shoot cum (yes) out of the chicken. Graphics aren't very good in full screen either and if you play in windowed mode the window is very small. It's not tragic, I've seen worse games but it's definitely not good.

Vector - It's a pretty nice game but it has some flaws. Controls are not always responsive, even when v-sync is off while playing in windowed mode. Maybe it's because you have to push the button in the same time in which the character is running and not, for example, finishing the animation of jumping, tumbling, rolling and so on but with so many animations it's hard to do that really. So often you just end up annoyed because the character didn't do what you wanted it to do. Also, for the very same reason it's hard to perform tricks even though you just have to push the "up" arrow to do that. And if you fail you have to start level all over again. I don't normally mind that (in Mechanic Escape it was perfect) but here it's kind of annoying. I like the music though, intro was cool and the gameplay's pretty nice. However, I wish controlling the character was better, more fluent and player friendly.

Stealth Bastard Deluxe - It's a nice stealth puzzle game, I thought there'd be more platforming really and relying on your reflexes rather than puzzles. If you're into such games (puzzles especially) then go for it, you'll probably like it.

Millie - Cute little game, a crossover between Pac-Man and Snake. If you're into such games then I can recommend this one as it's good.

Darksiders and Saints Row 2
( still waiting for 75 % for final fantasy VII and VIII, i loved them on psx )

Bastion ; BioShock ; Brütal Legend ; Clive Barker's Jericho ; Crysis Warhead ; Dead Island ; Don't Starve ; Skyrim ; Fallout New Vegas ; Far Cry 2 ; Final Fantasy 8 ; GTA 4 ; Hitman Absolution ; Metro 2033 ; Resident Evil 6 ; Scribblenauts ; Shank 2 ; Thief 4.

Yes, thats's a lot of boring solo games. Sometimes good games, but still boring.

Glad we don't need to talk about multiplayer games, I'd spit on Starbound again ! Oups, I did it again...

none. . .fortunately!

Potatoman Seeks The Troof - It's a pretty cool retro platform game but also pretty hard. You have 6-7 lives and if you lose them all you have to start from the beginning of the level. Play only if you like hard games. I might come back to it some other time but I'm not sure.

Yury - I'm a huge fan of old school platform games but this one is not good. First of all let's me say it has nice music. But that's not enough to keep me playing. Controls are terrible, controlling the character feels floaty. Game is hard but not the "challenging" type of hard but the "you have to retry this moment 100 times until you get it right/get lucky" which is something devs do if they genuinely can't make a game challenging. Terrible controls + hard, frustrating difficulty level give you the perfect idea of this game. There are also bugs present like when there's a platform moving left and right and it hits you it just moves you left/right straight into lava or spikes. If this isn't a bug then it's just dumb because it feels as you can't escape it so basically if you hit the objecting moving left or right you're dead. Other than that the game's pretty boring, you just descend down all the time avoiding things that want to kill you. I don't recommend this game even though it's very cheap.

Call of Juarez: Bound in Blood - Stuck in 1 of the gundraw fights.
No matter how many times I try I lose.
Even after dozens of tries, i still couldn't get past it, so I just gave up, uninstalled it, haven't tried again since.

Farcry 2 - I just got bored sometime into the story. Don't remember how far i made it, just never finished it.

Q.U.B.E. - Some of the later puzzles confused me. Got sidetracked and never went back to finish it yet.

There are a few others but that's just what i can remember going quickly through my steam library.

The Evil Within...I couldn't finish it. Haven't played it in a while so maybe I'll go back, pretty sure I'm near the end too.

Also Deus Ex and Just Cause 2 as well, I thought I was the only one, everyone seems to like those two games.

Crouching Pony Hidden Dragon - Rather bad old school game. There's nothing in it that would make me want to play it for longer than 10 minutes. Level design is boring, you have basically only two attacks (a kick and throwing shurikens), you can only throw shurikens in the direction you're moving in, graphics are bad even for an old school game and it's just boring, ugly and uninteresting.

Deadlings: Rotten Edition - It's a good puzzle/platform game. Platforming elements are rather easy but before you set out on a "trip" with a zombie you have to carefully plan what will you do with which zombie (there's a few kinds and each have different abilities). So it's really a game about planning your way and then executing it. Too much thinking for me right now but it's a good game, recommended.

Humanity Asset - Terrible game. Horrible graphics, annoying music, very bad gameplay, constant respawn of enemies and the whole general impression leave me thinking "how did it get on Steam?". I honestly can't think anyone would enjoy this.

Koya Rift - Very boring game. You just descend underground in each level and you have to destroy crystals guarded by enemies. Fighting with enemies is chaotic and boring, level design is terrible and the whole game is just not interesting.

Inside The Gear - Something like Crazy Machines but with worse controls, worse graphics, worse sounds and basically worse everything else. If you like puzzle games you might give it a try but don't expect anything special.

Rise Of The Argonauts - I'm a big fan of hack'n'slash games and I really wanted to like this one. I did like combat, it was easy but pretty cool and the slow motion bits were fun. Music was also pretty good. Plot seemed nice. And that's about it. Graphics were outdated though, dialogues were boring (and there were a lot of those, there's more walking and talking here than the actual combat which came as a surprise to me), there are also bugs present and the whole general idea of the game is that it's just very mediocre at best. I can hardly recommend it. Maybe if you really don't have anything to play, it's not a terrible game, just very mediocre and can be annoying and tideous at times.

None. and I have over 200 games in my library. I'm so ashamed of myself.
