I have at this moment only one game from Loki. I'm strongly considering Sim City 3000 as well. I realize the Windows versions are cheaper, but in order to best serve the community, and Loki, for their efforts I think it's only fair that I give them their just reward. Philanthropy goes a long way. Free software will always be around, as long as people want it.
Commercial software is only around as long as it's profitable.
To be honest, businesses will only support Linux if they see a profit to be had in it. And this will only happen if we support efforts to draw a profit. Develop a profitable backbone, and watch companies line up to support Linux. Acceptance by the home user will largely be determined by availability of commercial backing. So, I'm going to take a new approach, and put my money where my mouth is.
