Good job. Takes some time and effort to put this stuff together so I appreciate you taking the time. And in particular congratulate you for taking on board some of the constructive observations from your previous top 10 lists.
You don't mention handhelds in the OP. Are handhelds specifically excluded or is it just that no handheld games have made it to the top 10 of the genres listed so far?
Is this a snapshot list or are you going to make it dynamic, adjusting the lists when new AAA+ (in terms of Metascore) games come out and push the current 10th game down the list? With equal scoring games being at the bottom of a dynamic list (FPS list) if a game comes along and scores above the current bottom equal games then there's not much choice but having that list go to 11, and then 12 in the case of the FPS list (thinking of Halo: Reach and CoD: MW3 both likely to be up there on Meta). Then when KZ3 comes out those current 3 8th= games will all drop off 
As an aside (not necessarily a suggestion) it would be interesting to see whether Game Rankings (as a meta equivalent) would have a slightly different top 10. If not one or 2 different games perhaps games in a slightly different order.
I haven't played enough of those games to really voice an opinion on many, but Oblivion is one game I really didn't get into and I really like Fantasy RPGs, so I'll never understand why it got such a great Meta.
Happy to see Valkyria Chronicles there of course as my fav of the entire gen so far.
I really need to give Batman AA and Dead Space a go I think.
I loved RE2 and 3 and Code Veronica. But for some reason I haven't got a hankering for RE5. Maybe the mediocre movie adaptations have put me off.
I await the platforming list with interest.
