I'm also not putting down the 360 (as far as the games that are on it). I also know that gb are not the "be all all end all", but games are measured by size.
Kojima made a big deal about filling a 50gb dual layered Blu-Ray disc with MGS 4. Now obviously every game on the 360 can be done on PS3 and vice versa, but it's much more complicated than just porting things over.
Anyway, the amount of gb's give developers the space to bring their creations life. On another note I grow very tired of this discussion.
I do see where you're perspective is and I respect it. Had we been in person when this debate had started, it would have been much more fun and engaging, but a few days have passed and I want to move on.
