This thread establishes that one of the biggest mistakes in the 360 dashboard is the format option.
People use it as if it was a computer "clean istall will fix my crashing".
My friend when he got his used 360 called me and was like "I'll just format my hdd cause the other guys profile and saves are on there and I'll get rid of them" I was like heck no you'll lose hexic and any MS points and games he has downloaded. You can just delete the profiles and saves separately.
Well, there are two mistakes the format option and not having hexic as a download. But I guess they dont want core users with memcards to download it for some reason.
