games you regret buying

Dungeon Defenders. Maybe because I'm not a fan of tower defence.

And Stalker series are great. The spooky atmosphere, anomalies, mutants and artifacts are just great. Plus it is a FPS with some RPG elements. You'll die a lot in the beginning, but once you know how to aim properly and when you got the right gun, everything is fun.

Commandos bundle because of the shit version of steam
Dustforce because it isn't what i think it would be
And all the indie gala shit games

Bulletstorm storm for me :( Although the game is awesome, I had to "bug" it to get to play camping :( Stupid GFWL ... thats what i call anti-piracy when the pirated version works better (or at least works ! ) then original.

star wars knights of the old republic only because i'd already played it on xbox and i could spend my gaming time on games i haven't played yet, and then from dust and turba were both disappointing.

And Mount and Blade fire and Sword. I made hundres of hours in Warband but this FIre and Sword was a lot worse.

Hoard, bought for the achievement. Looks like I won't be doing anything like that for the Steam Sale. =(

I know one game i dont regret!!!

WOODCUTTER SIMULATOR!!

what :O those are the 2 good stalker games! i was just playing stalker COP :D but titans quest also? well its is in my wishlist, i did play its demo manymany years ago, and now i wanna buy it sometime.
but i regret buying those aaaAAAAAaaaa games and especially 1,2,3 kick it. lucky form me i got the dejobaan pack, so it was all together not so expensive.

Breach.

Monday Night Combat

and some games that I bought too early (bought them on sale but haven't played them before their 2nd sale when the games were even cheaper)

Total War Shogun 2. Don't like the setting. Hoped this fade away when playing, it didn't. Battlefield 3: damn EA, too many DLCs and Premium bullshit. Worst buy ever. Piece of crap, crappy publisher...hate them...cancer for you...wait..you ARE cancer for us...

STALKER SoC & CoP - far from bad, but playing them I realized I really like the sunny outdoors in my games - these are way too gloomy.

PoP The Forgotten Sands - To be fair, the page says only Win2K/XP are supported, but a number of people said it was fine on 7 x64, so I thought I'd give it a go while waiting for the next AC. Well, no go, I got a weird bug where Prince won't stop attacking after a certain combat near the beginning. Also, requires unofficial patch to get widescreen support, which decreases the FOV and stretches the menus.

GTA4 for PC - awful PC port.

Breach - doesn't even work (never made it into a server at all)

Magic the Gathering: Duels of the Plainswalkers 2011 - deck building? You mean being able to use a sideboard? Yeah, we got that! What, you wanted to be able to tactically select what mana you wanted to tap? Nope. Don't get me wrong, this is a great game to get into Magic if you're a newbie. I've been playing since 3rd Edition and it was unacceptably crippled for experienced players. (2012 seems to have fixed these big problems, but fool me once...)

Need for speed: Hot pursuit(The one one steam) I bought it thinking I would love it as much as I did with the original, no I disliked it very much and realized I liked things like shift and other similar.

Sorta on this one: Civ 5; I dunno, I love the civ series, played all of them. But I really dislike civ 5 compared to 4 or earlier, I dunno why.

Dungeons and Dragons - Daggerdale. Just... ugh.

How can one regret to buy Stalker?!

Kane & Lynch 2: Dog Days. And I only got it for like 7€. Still not worth it.

If we're talking about Steam related games I bought I'd say:

Greed Corp

simply because the multiplayer is on life-support, but I wasn't too surprised, so it wasn't my greatest regret ever... oh no... there's only one game that single-handedly managed to change my views about buying a game soon after its release:

Jade Empire (for XBox)

Biggest disappointment (and waste of €60) of my life. My expectations were so high on this game... too high. I will never forget that horrible shoot-em-up minigame, those repetitive fight tactics (jump-dodge to victory), those many backtracking quests, that rushed plot towards the end (of an already short game), those bland multiple endings and that shitty prologue.

The game was okay-ish, but if only I knew that before getting hyped about it... if only I knew...

Wargame:European Escalation

I'd played another game of the same genre by the dev, but this one was on sale for 20 bucks so I bought it. Terrible game.

S.P.A.Z., Dungeon Defenders, & City of Heroes

sniper ghost warrior and call of duty 7+8

I regret nothing.

Zero Gear. Devs did not release a single update, and the 4 stock maps got boring within 2 days. It's actually the only game in my library I do not have installed xD

"Saints Row The Third", Borderlands and GTA 4...
