help between two completely differ games

[blu-iscrack]

ok i know these games are completely different but if u had to choose between GTA for the PS3 or mario galaxy which would u pick. I asking cause I recently bought mario galaxy used from game stop and not sure if i want to return it for a pre order of GTA. I played a little of galaxy but not enough to get a feel for it and i might not even get a chance to play it until its too late to return it. thanks to all that reply!
