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 s… - Michael Simms

The biggest challenges, technically, are 3D graphics and Networking. Network interoperability between Linux and Windows will rarely happen, because companies often use the proprietary Directplay library which cannot be ported over to Linux. We have created a multiplatform alternative, called Grapple, and we hope that over time, some Windows developers may pick this up to use in their titles, allowing cross platform multiplayer.

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.

Things like a spreadsheet and graphics package mean that people can use their computer for working. Games mean that people can ENJOY their computer. If all you have is productivity apps, then Linux will be a fine OS for work, but who is going to really want it around in the home if all they can do on it is work.
