Halo 2 Already Pirated

[GameMaster]

I'm not really sure. I mean, in terms of computer measurements, how much does a high-end game like Halo 2 consume? Is it a gigabyte, 50 gigabytes, 500 mb? I've never downloaded something that was even a gigabyte so I don't know if it could really be done in one night. Ignoring the factor that other people with the file would be online all night so you'd have a steady download rate.
