Witcher 3- The game redefines the rpg genre and goes to its root, even the sidequests quality is very high, I was doing this werewolf mission and it looked like a main mission for most AAA rpgs, 10/10 would play again.

Arkham Knight- ONLY if you played the previous 2 Arkham games, try this one. Perfect end to the trilogy and is darker than the previous 2 games, its broken on PC(third party dev port and delayed lel) 9.5/10

And the last game which I haven't played but it'll be Fallout 4

Easy!

Mass Effect 2 blew me away, and Besiege was the best seven bucks i´ve spent this steam-year (so far).
Witcher 2 is pretty good aswell.

what kind of genre of games do you like though?

TF2 is always a good time, for me at least.

Nuclear Throne is my go to game as of lately. You can "beat" the game in about 15-20 on average but looping (which makes the game way harder) can mean you can go on forever. Randomly generated fun.

The following games I tend to go back to. These games I have had fun but then I get bored but come back eventually to.
(PC): Luftrausers, BattleBlock Theater, Spelunky, SpeedRunners, Cloudberry Kingdom

(Consoles and Handhelds): Smash Bros. (any of them), Mario Kart (any), Megaman (any).

(Android / iOS): Rayman Jungle Run (Android and iOS), Jetpack Joyride (Android and iOS), Ridiculous Fishing (Android and iOS), Super Crate Box (iOS), Jones on Fire (Android and iOS), Peggle (Android and iOS, There is Peggle on PC as well)

Most of the games I've played this year were fun, here goes a list*:

• Rogue Legacy,
• Binding of Isaac: Rebirth,
• Dungeons of Dredmor
• UnEpic.

*not listing mmo games as requested.

The Witcher 3 is probably my favourite game I have played this year.

But if we are talking a little bit less obvious I thought "Her Story" was outstanding and well worth a go as something a little bit different.

Axiom Verge is also a game I really enjoyed... nearest you are going to get to Metroid not on a Nintendo console.

and my hidden indie game was Porcunipine which is a multiplayer game which reminds me a little of the old Snes Bomberman games but it is the most pure multiplayer fun I have had all year.

Dark Souls

battleblock theater

The Cat Lady - A surprisingly deep and dark point and click game.

Spec Ops: The Line - What seemed like a typical third person shooter turned into a highly emotional psychological experience.

The Forest- A fun survival game where you're left stranded on an island trying to defend yourself from cannibals
Rising Storm/Red Orchestra- A magnificent WWII fps
Civilization 5- A great strategy game
Star Wars Jedi Knight Jedi Academy- A dated yet still great game about the Jedi and its focus is on lightsaber combat
Gang Beast- This is only if you have friends willing to play with you in your house, its a local co-op brawler

I've liked playing Faster Than Light and Prison Archtect, low graphics games but very fun
FTL get bored quicker but Prison Archtect have a lot of options with mods and that.

GTA V is pretty sweet =P

Gone home mechanics are so much fun, but kind of short, a map generator or something like that would do wonders for it.

and New Vegas, that is such a great RPG, replaying and im still finding new stuff.

AllGamesIGotIn2015

I'm currently playing LEGO LoTR and it's awesome!

Most of the "funniest" games for me are multiplayers, i got kinda bored with single players right now...
Some of them:

Risk of rain
Battleblock theater
Double dragon neo
Kane&Lynch2
Borderlands2
HeroSiege

The Binding of Isaac: Rebirth- A story about a naked little kid using all kinds of demonic items to kill his mom.
Nuclear Throne- Weird mutants trying to irradiate and transform themselves to get to some throne for some reason
Payday 2- Robbing simulator
Super Meat Boy- Retro-ish; very difficult
Hotline Miami Series- First game had more story and less insane. Second has a shorter story, but more insane action and better soundtrack (in my and I'm guessing a lot of other's opinions).

The Vanishing of Ethan Carter is probably the game that has most impressed me this year. I can't remember another game that so constantly left me in awe of how gorgeous it is. If you're looking for a game with action/fighting of any sort, look elsewhere. It's a sort of point-and-click, relatively-open-world, tear-jerker (at least in my experience) murder-mystery adventure. Fairly short though; took me about 5 or 6 hours to complete, and I imagine with less exploration it could be done in 3 or 4.

Terraria is so fucking good right now. Just got updated, and has a ton of new stuff. As for how long it's fun for, it depends on how much you like building/survival/RPG type games. So far it has managed to entertain me for several hundred hours, and I've yet to tire of it. I'm working on building a new base at the moment. :b

Fun fact! It was my first win on Steam Gifts. One of my faves, too.

Talos Principle is sooooo good. I never hoped that they make games THAT good in 2015.

Also if you like space, rpg, quests and even strategy then go for Space Rangers.

If it is ok with you for some old and strange but great games then you have to see Vangers.

I can't remember for this WHOLE year, but here's a list of the games I've been playing and enjoying in the past months:

1. World of Guns: Gun Disassembly - Assemble and disassemble guns. Not really a game, more like a simulator.
2. Eternal Senia - A free to play single-player RPG game on Steam. Surprisingly good.
3. Dishonored - Oh my god this is now on my list of favorite games. :P
4. Floating Point - Relaxing free to play single-player game on Steam. It's really fun and extremely relaxing to play.
5. One Finger Death Punch - Stickmen, epic fighting, two buttons. No comments.
6. Half-Life 2: Episode 1/2 - Yay, Half-Life 2.
7. Assassin's Creed II - stab stab stabby stab
8. Sonic & All-Stars Racing Transformed - Mad local co-op fun with my little sister and my brother. I might not play it often, but when I do, it's great.
9. To The Moon - :3
10. The Treasures of Montezuma 4 - For once, a match-3 game which isn't boring me out of my skull.

I think that 10 is a good number. It's a really nice number. I like it. I'll stop here.

SMITE, Terraria (1.3 update came out recently), Diablo 3 (New patch coming soon™), and PAYDAY 2.

Started TESV: Skyrim. Damn, I should've bought I sooner....
