Another method for keeping the save count low, would be doing something like a staggered 2 save system, where you still go with auto-save/quick save, but when you want to make a new manual save you do it by a fairly static name like current1/current2 and then alternate between the 2, rather than letting the game auto-name saves and eat up your gigabytes.

Either that or I should just get a 1.5 TB hard drive and use that for my main system drive, and just not care anymore.
