Some PS3 cleaning

There was some error in Prototype that kept telling me I didn't have 700 megs of space for the install that drew my attention to the fact that while I did have well over the required amount of space for the game, I only had about 4 gigs of the 80 (read 74 usable) left as free space. I deleted my Ninja Gaiden Sigma install which gave me over 10 gigs and the game installed obviously, but I didn't think the hard drive would fill up so quick with just game installs and DLC. I think RE5 and DMC4 were the biggest offenders with over 4 gig installs. MGS4 was also a big offender. Surprisingly with all the DLC Burnout has released (I own Party, Cops & Robbers, Legendary Cars, Toy Cars, Special Cars, and the new Big Surf Island) it's under 3 gigs.
