360, though I can't think of a good casual game for either system.

They're both pretty even, but the 360 has the games atm. I picked a ps3 because of the games I will be playing in the near future (MGS4, FF13, and so on), but my pc is my "360"-or i could just play my roommates 360.

I would say MS.

The Wii. /troll.

Right now, the 360 does, no doubt. They will be rather even after this year though imo.

I assume that a Hardcore gamer wants more than 1 game. Amount of games is more important than Quality. Thats not true however quality is subjective.

Half of the ps3 games you've mentioned don't even have a solid release date, unlike almost all of the 360 games.
