That is debatable. I myself think that it is the best others disagree.
Pros:
Fun game play
Good story
High re-playability
Many unlockables
Many weapons
Great Graphics
A lot of Easter Eggs
Cons:
Repetitive
Game Play to cut scene ratio uneven - 75% Cut scenes 25% game play
Controls and gameplay very different from previous games
PS3 is not a game it is a Game Console and as Sony says a whole lot more.
NO it was aclaimed the BEST PS3 game!
the best ps3 game is What ever you think
Infamous 2
Ps3 or psp are the best.
In my opinion Dead Island is the best, it depends on what you think of the game.
uncharted 2
Demon's Souls
Killzone 3
fifa 11
FALLOUT 3
battlefield:bad company 2 is the best game of 2010 and the best multiplayer game
The best adventure game would ultimately have to be Little Big Planet.
