Knoppix game CDs is a good idea as a method of selling Linux games. Transgaming is marketing WINE-X for the gaming market. A commercial version of Knoppix with Transgaming's WINE-X libraries and a game on it could replace Windows gaming. Because there are so few Linux games, it is unlikely a typical gamer would buy and install Linux specifically to play linux games, and so few games developers will write Linux games. However if the game comes with it's own OS environment on CD and doesn't touch the Windows installation, then gamers will buy it because as far as they are concerned, it is just a game CD like any other. For games developers, having a controlled environment to run the game in and not having Windows hog resources may be attractive. The Windows hard drive can be used if necessary by using a filesystem running under the Windows filesystem or by repartitioning the hard drive.
