Yeah I did buy it. Just found it a little odd that this is the only game I have requires the disc to play. Also a hassle installing too. Kept opening Catalyst Control Center for some reason. Thanks for the reply.
The reason they require the CD is because of pirating. A lot of people would otherwise copy the game for their friends to play, even though they didn't buy it. Still, due to these hacks, and pirate sites, people are pirating them anyways, but that simple requirement does stop a few people from pirating their game.
