Which game I play now ?

The only two games from that list that I didn't play even though I have them, is Van Helsing and XCom. With that said, your next game should be Spec Ops: The Line for sure. If you never played it before then you are in for a treat, such an amazing and underrated game.

X-com is my genre of choice. After more then 2 decades there is finally a sequal that is up to par with the original and it's first sequel (TFTD). They took the frustrating elements out and added some really good elements to it. I can play that game for days. My 2nd choice would be thief, I did only play the original more then a decade ago but it kept me busy for a long time.

Darksiders, Spec Ops or XCOM

If you want to play a game with a great story, Spec Ops: The Line.

Hitman and X-Com are both great in their own categories.

Dishonored / Skyrim missing in the poll, poll not valid :o

Skyrim..
Oh, wait.. no skyrim in the poll (ಠ_ಠ)

XCOM if you're into turn-based games then

Played only Spec Ops The Line, and that's the game which I definitely rocommend to you :)

I have played most of the games in your list and I like all of them but I like Hitman the most. :-)

van helsing 1, then 2, then 3 :3

So the winner is Tomb Raider. But when i finished this now i have 2 games to play: Spec Ops (i read the comment and i think it is a very great game) and XCOM. Thank you all for the support and the votes ;)

xcom if you want to be busy with your next game for a few weeks :P Lara or Spec ops if you want a relatively shorter game right now :o

all of them are nice, van helsing is fun and full of references :D
