I am looking into getting a modded 360 but I am wondering how big the games get. Hope I am not asking anything against the rules but here is my question. How big is a 360 iso or whatever you call them if you download them? What is the least expected size? Asking this because I have a psp and those isos get around to 1.50 GB and if xbox's games are way bigger than that then I can't commit to it. My internet provider would charge me like crazy.
