Shivering Isles was 994mb. Point Lookout was 370mb. So OWB is nearly twice the size of PL and only 30% smaller than SI. Awesome
Edit: @Maxsil, They make 250GB harddirves for the 360, but you effectively get 214 for some reason.
Huh, i wasn't aware of that, though i despise this generations consoles, so i guess i'm not the person to answer these questions
