I want to play some Valve games like Team Fortress 2 and Counter Strike. Since Mac can't run those games then my only option is to use Bootcamp. But I don't have the OS X disc only the Windows Xp disc. I've heard some people say on the "windows on mac" forums that windows all of a sudden stopped working and they had to reinstall OS X onto their Mac because they couldn't choose between the windows and mac partition, there was some type of error. But since I don't have the OS X cd that would be a problem for me if my Macbook was ever to mess up! Is there any other program where I can run Team Fortress 2 and Counter Strike on my Mac without having to use Boot Camp?
