Well with 2 - 3 hour long battles you could fast forward x1 x2 x3 x4 x5 or whatever. An example of a bad way of recording: -C&C Generals and Zero Hour (Normal and fast, its so slow in 1 hour games) An Example of a good or good enough way of recording: -Rome Total War (I think you can free roam and speed up or speed thinks up even more or pause) -Battlefield 2 (Free roam your actions and speed up and speed things up more) I dont have 60 GB to spare but I do have 15 gb left of space and I bet people have 20 gb and under I have to much media on my computer thats why (Music, videos, and pictures and cant forget games).
