come again??
ff12 is about 4 gb and it'll take you at least 100 hrs to finish it all together with the sidequests
you can say Blue Dragon VS Dragon Quest i can belive it
but FF alone can take ps3 to the top
other than this i don't think ps3 will reach the top while xbox is getting more popular-cheaper-exclusive games
who knows we might see FF13 on xbox if ps3 died or somthing
