The 2 games you most liked?

Silent Hill 2 & Planescape Torment.

Saper & Solitare (yes, those MS games)

Cod 2
Mirrors edge

The Last Of Us for story.
Goldeneye (N64) for gameplay and its influence.

Megaman X and Half-life

Quake II and Command and Conquer: Red Alert 2. Honourable mentions include TF2, Killing Floor, Deus Ex, earlier Command and Conquer games (pre-RA2), and probably some more that I might post later if I feel like it.

GTA V & GTA V

Bad rats, Revelations 2012

Digimon World 1 and Dark Souls.

Fable: TLC and Beyond Good&Evil

Skyrim, Don't Starve, Mafia 2 ..

Portal 2, TWD

Bioshock and Mirror's Edge

Thomas Was Alone & Bioshock Infinite

The Witcher & Gothic

Starcraft and UFO: Enemy Unknown.

First I had in mind Diablo 2 & StarCraft 2

Then I also thought about many other games I played before: Fallout 1 & Planescape: Torment, Blood Omen: Legacy of Kain & Tomb Raider 1, The Witcher 2 and Mass Effect series. Well, I still like them, but D2 took months of my life, while SC2 made me feel lika a happy baby getting his toy when I bought it :)

Bastion & Mark of the Ninja

Probably black ops 2 and BF3.

Fallout 2 and New Vegas.

minecraft,lol,dota,tf2

Two Worlds II & Age of Pirates

Final Fantasy VII and Final Fantasy VIII

1. Left 4 Dead 2 (The best game ever, you can't beat it)
2. Call of Duty Black Ops (I'm not a COD fanboy, but I liked how it was a lot slower paced than the other Call of Duty games)
