I think you can re-install just the maps to correct any problems. I will check on it and report back.
For the choppers/planes I highly suggest adding a USB joystick. I have a simple Logitech Extreme 3D Pro I picked up for $20 locally. Since you can program the vehicles independant of each other and your player actions I was able to configure it and actualy fly them. It will still take some getting used to put it allows it to have a more familiar feel.
Also something I read online said that the downloaded version sometimes has problems with the patches and some other “mods” (i.e., widescreen mod). Apparently it has something to do with steam?
OK so last roll call then for who needs games? Bones & FU have theirs. Anyone else? I will be ordering today.
