Things like a spreadsheet and graphics package mean that people can use their computer for working. Games mean that people can ENJOY their computer. … - Michael Simms

Most games that we are approached with are too close to existing open source games for us to publish... we have no real desire to compete with open source products.

If they come to us, we do all of the work and take all of the risk. They have no financial exposure. Making the client themselves is always risky. However you cannot look at it in terms of money only. When a game is ported to a second platform, it almost always exposes bugs and problems that would otherwise have been missed, as the developers have to re-work portions of the game. This will mean that creating a Linux version will increase the stability of the Windows version, and increase the quality of their core product, a fact that in itself may justify the cost of a Linux port.

I personally believe open source is most important is in the operating system and in file formats. As long as those two things remain open source you can never have a monopoly. No company can dominate by any means except a superior product, and that puts the choice back into the hands of the public.
