I'm thinking about getting Unreal 2. The thing is, on my 38 gig hard drive, I'm down to just over 6 gigs. The over twenty some odd gigs are used for a DV film I'm making. I'm really hankering for a solid FPS experiece, something I can sink my teeth into for a time, and supposedly that's U2 is supposed to be. But with such limited HD space, I don't know if I should risk it. Any suggestions??
