Unfortuantly, i doubt people will listen, Due to the complexity of installing for the short attention-spanned 13 year olds that buy the games and the fact it would take a lot of work converting to Linux, Making a simpiler version to install, and the factor of how much will be earned in the end, I dont think it will happen

Your best bet atm (Which is actually a good one if you actually want to play games in the first place) Is to use a emulation such as Cedega, Wine tools, or other programs to run the game.

For Knoppix i believe Cedega is best, go to your hard drive and let it read your games in windows installed.
