Support for these formats would be nice: Valve's GCF/NCF Dynamix/Sierra .vol files (there are two different versions) fzip files (I don't know what format these are, can't find ANYTHING that will open them)
Seeing as how I am always that .01%, I will not be telling my setup to skip loading anything. However, since my installation is already about 850MB, I might as well expand a bunch of stuff so I will not waste the majority of a DVD.
