Endless Ocean - 8.3 > Fallout 3 - 8.2
Valkyrie Chronicles - 9.4 > Bioshock - 9.3
Tales of Vesperia - 8.8 = Halo 3 - 8.8
Civilization Revolution - 8.7 = Uncharted - 8.7
God of War: Chains of Olympus - 7.9?
With the VGChart reviews, you really shouldn't care games from different systems (unless they are PS3/Xbox 360, IMHO).
Endless Ocean is great. I don't like games like Fallout 3 - at least not on consoles.
I've never played VC. Bioshock was not a good game, IMHO. It was about how Ayn Rand was wrong - which is crazy because she was right.
I've never played a Tales of game (including Tales of V). However, I don't like Halo 3 at all. It was a pretty good game by all accounts though, and it has a good score.
Uncharted looks fantasic. However, Civilization is one of the best series of all time. Of course, I won't play it; RTS on a HD console - no thank you. Neither one have a bad score, so I don't see what your point is.
I have no idea on God of War because I don't play games like that.
Anyway, there is more to reviews than numbers. Make sure to actually read them. VGChartz reviews are much more informative then reviews from many other sites.
