Made a topic like this a long time ago.

I'm playing quite a few

-Persona 3 and 4 (i'm on the final dungeon of 4, haven't touched 3 yet)
-Donkey kong 64
-Super mario 64
-Legend of zelda Majoras mask
-Super smash bros brawl to get hyped for smash 4

Battlefield 1942
Battlefield 3
Red Orchestra 2: Heroes of Stalingrad
Supraball
Spore: Creature Creator
World of Tanks (eventually, not the best game for me)
Skate 3 (PS3)
War Thunder
RollerCoaster Tycoon 3

That's all coming in my mind, quite a lot actually.

Assassin's Creed: Brotherhood
Deus Ex: Game of the Year Edition
Grand Theft Auto IV
Grand Theft Auto V

That's all I can remember right now.

Gta V
Borderlands 2
Zone of the Enders HD
Left 4 Dead 2
Minecraft
Castle Crashers
Happy Wars
Fallout New Vegas

SCP - Containment Breach

this is too easy

Plague Inc: Evolved
and also a bit of "The Binding of Issac"
