This year I havent purchased many games from 08, Ive been mostly going through the backlog. From what I have played, this is what I think:
1. Fable 2 - loved the original, sequel did not disappoint.
2. Braid - dont know what your policy for XBLA games is, but Braid is great.
3. Lost Odyssey - filled a huge RPG void at the beginning of the year
Award X: The Orange Box, specifically Portal - words cant describe the awesome
handhelds: dont own any.
