The best games you have played

Kingdom Hearts II
Kingdom Hearts: 358/2 Days (mostly because of the story line - actually the whole Kingdom Hearts story line is amazing)
Final Fantasy X (again, mostly for the amazing story)
Assassin's Creed 1 (haven't played the others yet but they seem very promising too!)

Child of Light - I haven't played it myself but I'm watching a Let's Play of it on YouTube and it's really beautiful in my opinion. I definitely want to play it myself.

Portal 1-2
Football Manager 2012
London Racer Destruction Madness

Dota 2?

The Rachet and Clank Series, The Walking Dead Game, The Last of Us, Beyond Two Souls, Minecraft

I'd have to say The Walking Dead: Season One. I haven't played the second season yet, but I ensure it is great. But the fact that you can choose what you say to domino later effects and the fact that it is so emotional.. It's amazing.

Skyrim, GTA 5, BRINK, BattleField 3, Fallout 3
