What exactly would be the issue with that though? Most games now are around that 2-3gb mark and if you don't have room for it then someone needs to do some cleaning...
I got you beat hawkn with 1.5tb free and 500gb used :P Terabyte externals are ridiculously cheap now adays.
Ah I never thought about it being an internet problem. Buy the boxed version then? Pretty sure there's a boxed version... If it isn't available in your area then I don't know. Download it over night? That's just one of the flaws of downloading a game instead of getting a boxed version I suppose.
At least 5 gigs would not surprise me.
