Downloaded from FileRush in about 36 minutes. Installed.
Some annoyances:
For Nvidia card users, you have to install the included 77.30 drivers, or you'll get bombarded with an annoying message in the game.
Video options for me only went up to 1152x768 resolution... I have a GeForce 6800 Ultra and a 19" LCD with 1280x1024 native res.
Have yet to play the game, about to reboot after installing the included drivers.
