If Trials Evolution, The Witcher 2 and Halo 4 aren't core games, then I don't know what am I playing :) Bullshit is always bullshit :)
I don't feel the need for exclusive games that are poor in comparison to big multiplatform titles. That's why I will pass on every exclusive PS3 game until new God of War is on the market. That kind of exclusives I will buy.
