[quote name='lt_homer']anyone know if halo3 odst is like halo where its better to play it off the disc? same with the multiplayer disc?[/QUOTE]
Better is relative, because I'd never run anything from disc on the 360, it's so loud.
But the only reason Halo 3 loaded faster from disc originally is because it was made prior to the install to drive feature, and cached to the hard drive (which of course doesn't apply to ODST). Installing to the drive meant it had to copy from one part of the drive to another, which is the only reason it could be slower.
I have to wonder if Microsoft could just get rid of the cache area of the drive or something, or let you trick older games like that into thinking there was no hard drive installed, so they'd load faster.
