Starfoce is a copy protection system very aggressive. It's actually a driver that installs itself with the games that come shipped with it, and originally it didn't uninstall when the game was uninstalled; this invasive copy protection sucks.
POP 3 on xbox itself is amazing and the game is so different from the other ones that its awesome. im thinking of getting it for the pc as well. once i get an adapter so i can connect my xbox controller to my PC. then ill be set to go.
this is indeed an awesome game, too bad it doesn't really support widescreen,
only selectable WS res is 1920x1080 on my WUXGA but that's a bit high for my 6800go. playing at 1600x1200 now and performance is pretty good so far. average 50-60fps.
edit: ok i managed to get more WS res to work, by editing the hardware.ini file, only 16:9 res worked for me and they aren't very good, because it just chops off the top and bottom so you see much less on screen.
