Errr.. its time I should hop in.
The idea of rating a game/listing top x number of games sounds nice but it do have some drawbacks too:
-->Every person has his/her own taste He/She may love Game A instead of Game B (even though B was perceived as AAA title).
-->Meta critic score is the most valid score in my opinion, but it still IS the score given by gamers around the world, having their own tastes.
-->Having a list of 100/200/... is good but is cumbersome to maintain, coz each year the scenario changes, and if we wish to create a new thread each yr, no one would ever notice previous games (telling this after my personal exp)
I'm still ready to help in any way its required.
