GameRankings, folks over at GameFunk have prepared the nice little chart above. Apparently, Wii games don't get that great of marks from reviewers. Compared to the marks of games on other consoles, it makes the Wii's library look even worse!
Here's the numbers:
- Xbox 360: 374 games: 26% good, 24% bad
- PS3: 122 games: 33% good, 17% bad
- Wii: 189 games: 11% good, 37% bad
Also, keep in mind that the PS3 and Xbox 360 don't have Metroid Prime 3: Corruption or No More Heroes. So they pretty much lose.
