I could see that Final Fantasy may get quite some undeserved high scores. (only maybe though)

CoD 7 shouldn't be on the list at all. There is no reason this could be overrated.
after Modern Warfare came out no reviewer praised World at War nearly as much as the previous Call of Duty.

I think all of those games are going to be both fantastic and overrated....we gamers love to hype things (not that i'm complaining cause i do it too). my vote goes to COD although i was thinking about going with zelda.

I say COD7...since I generally feel that series can be overrated. (I love the series....but don't think it should be 90+)

I would have said Halo Reach....but honestly don't know much about it...
I bet everyone thought I would say Final Fantasy 13 and they might be right in a few years, but right now this is it.
