Should I sell these ps3 games for this brand new ps3 game? Or keep my games?

I reckon you should hold off the game for longer and keep your games. because by the time your dad pays and you finish playing the game, the other game you wanted but couldnt get would be cheaper and you would save money. i wouldnt sell my games even if i dont play them, because sometimes i like to give it to people for borrow or something etc. but yeah hope this helped :)
