I have never ever seen a game that ties itself to the hardware configuration.
All games from Trymedia/Trygames.com do this. All games from IGN/Gamespy's Direct2Drive do this. So, DON'T
buy rent games from there! If you upgrade so much as the BIOS on your PC, you will have to reactivate which eventually means paying all over again.
