The best game you have ever won

Alan Wake and Mirro's Edge!!

the less worst is E.Y.E: Divine Cybermancy

Fortix !

Mirror's Edge

I won Counter Strike complete about a month ago but sadly the giveaway turned out to be fake. There were about 5000 entries too which made it even worse. Apart from that, I recently won Guacamelee! gold edition which is pretty good although I haven't had a chance to play it properly yet.

Super Hexagon

I WAS BLESSED BY OUR LORD GABEN TO WIN FORTIX NOT ONCE, BUT TWICE AT THE GREAT FORTIXCEMBE HAPPENING! BLESSED BE GABEN AND HIS PROPHET DELTABLADEX!

Civilization V

Skyrims

Really hard to choose, too many good games. But Divinity: Original Sin is one of them, for sure.
Also Dark Souls

Hitman Absolution

Dead Space. I'm actualy enjoying it alot.

Either GTA:SA or Hitman: Absolution.

(Absolution is absolutely not as good as most of the earlier games in the series, but even a below-average Hitman game is still much better than almost anything else.)

Bioshock

Sleeping Dogs!

Deponia complete pack
too bad the game is bugged, hope a patch will come out soon

Dear Esther, and I still haven't played it yet even though I won it 3 months ago!

FTL: Faster Than Light

Black Flag

DayZ

Shattered Horizon :)

Divinity: Original Sin and Civilization V: Complete Edition.

one amd never settle gold with which I got sniper 3, alan wake and murdered: soul suspect

LEGO Batman /o/

Metro Last Light Complete Edition and Dieselstormers. Great games :)
