I have several games that don't need to be installed, but simply extracted (or not) to a location out of the rar or zip (or ace, of course) file. My computers hard drives are small (20 and 34 gig), and all of the games are small enough to fit onto a DVD (or CD). What I am worried about is the fact that it may lag (or not work at all) because it may read a lot slower than the HD. What do you think? I don't want to waste a DVD, otherwise I'd test it out.
