Portal

Rocksmith, Orange Box, Resident Evil 4, Resident Evil 5, Street Fighter 4, Super Street Fighter 4:AE, Street Fighter x Tekken, Prince of Persia Trilogy, Dead Rising 2, Unreal Tournament 3, Unreal Tournament Anthology, Jade Empire, GTA Vice City.
Well, most of them is shared with my brother. I have more games for consoles, mostly PS2. I have some nice games in my console collection.

To be honest ... well... none :D

when i moved to australia from the US, we couldn't get internet hooked up so i bought a boxed copy of Civ V thinking like an idiot that i wouldn't need to get online to get it running. Needless to say, i spent a lot of time staring at the box and waiting for the internet to get connected. :P
