The best exclusive titles are on the Playstation 3

[Neoraf]

OP: That is your opinion.

In mine, MASS EFFECT alone destroys the PS3 list.

And you should never give a damn about the so-called AAA qualitative... it's subjective.
On 360, you must add:

Lost Odyssey
Braid
Tales of Vesperia
Star Ocean 4
Viva Pinata
