first off, even PS3 people i know admit that VF5 is better than Tekken and its multiplat.
Gears of War, Forza, Mass Effect, Too Human, yes Halo, bioshock, and that JRPG coming up that i personally dont give a damn about (i dont like JRPG at all).
-VF is not ps3 exclusive and Tekken is more well known
-The 360 games you listed are not well known enough.
All of the games on that list is a part of a series so those names have been out for a long time and all of those games have sold well and been pretty good.
Let's say I talk about games with some friends that play games maybe 6 hours per year. If I mention any of the wii games they have probably heard of them and know it's a game, I think it's the same with FF, Tekken and Halo but they are not as famous as the wii games. But if I mention Bioshock they could think it's a movie.
Gran Turismo probably belongs on the the PS3 list.
