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.

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.

The most popular games for Linux are evenly split. First person shooters such as Quake 3 and UT2K3 sell more copies to start with, but they trail off when the next graphics leap happens. Strategy games like Alpha Centauri still sell well for Linux, they dont sell as fast, but they last a whole lot longer. Kind of like the hare and the tortoise
