I only have a 60GB HD and to be honest it doesn't go as far as it used too.
Anyways, I had this game installed it was around 11GB. Now I haven't played in a month and I know the DLC is out. I had about 5 gigs free and it starts patching, it downloads a couple patches and now its saying I need 3.3 gig free or so to continue patching. MY game is at like 13ish gigs and it was 3.3+ for gigs? I mean damn, how big is this game going to get? It is really about a 15-16 gig full install now? OR just it just need extra space to work, but that's pain in the ass too for only a 60gb HD.
well I deleted everything and re did it, it only 6.9 GB patched.
When got the game the first time i installed it through the xbox menu like every other game, then when fired up the game it installed again automatically. I guess I had 2 installs going with multiple patches which is why it took so much room.
The redo took about an hour total between installation and patching.
