I just got a vita and I heard psp games look way better on the vita. Do they look grainy at all since it is a higher res screen? I have a psp and I was wondering if it would be worth it to rebuy ghost of Sparta, peacewalker, Valkyrie Chronicles, pes3 and monster hunter. Is it that much better when I already have the games? Will my monster hunter game save transfer to my vita? It is a hacked psp and I think the region for my Monster hunter was Europe.
