According to Metacritic:
- Super Mario Galaxy
- Resident Evil 4 Wii Edition
- Metroid Prime 3: Corruption
- Zack & Wiki: Quest for Barbaros’ Treasure
- Guitar Hero III: Legends of Rock
My take: Super Mario Galaxy the best game of the year (across all platforms), RE4 overrated, MP3 slightly overrated, Zack and Wiki underrated, GH3 about right.
