Nice stats.
Yup, IGN has been my reviewer of choice for a long time now - and I find that my opinions closely align with their reviewers (in terms of score, comments, etc..).
1UP & GameSpy look like they hate the Wii. Then again, it looks like GameSpy is just a hard marker - leaving just 1UP (pro 360, neutral PS3, hate Wii).
Play magazine isn't much better.
Another way to look at it:
Wii: +1, +/-3, -6 (total -5)
PS3: +2, +/-4, -4 (total -2)
360: +4, +/-1, -5 (total -1)
...
Want to add some other sites to that list? Joystiq?
