I got the collectors edition and when installing it said I needed 64mbs more of free space to install. I unninstalled a few stuff but I dotn know why but with every uninstall the number went up from 64 to 124mbs needed. I had 1GB free space and after uninstalling 2 games it droped down to 700mbs free space. I cant even test it to see if it will work on my 16mb video card.
