Wow that is a hard one.Hmmmmmm..... first of all you have to know the ps2 was made some years after the 64.So the graphics are ALOT better then the 64.But i got to say the 64 was way ahead of its time.So I guess I would go with the 64 because the addictiveness that it has I mean Ive benn playing it since 1996 when it came out .
