I find if you're targeting Windows, Linux, and Mac OS X right from the start, your code will probably work anywhere else that you might try it later. Writing code that is cross-platform from the start requires more discipline, but I find it is worth the effort.

What I do for a living is somewhat like mercenary prostitution. I spend a lot of energy trying to find games to bring to alternate platforms, like Linux and MacOS, and in my free time, I work on various open source projects, and other freebies like that. So I guess I'm a hooker with a heart of gold, sorta.

I think [Wine] will be, at a minimum, incredibly useful to archeology, like DosBox has been for playing Wing Commander. Certainly it has been known to save the day with modern titles, too. But to have it as the agreed-upon way to how you play video games on Linux is completely unacceptable for several reasons, both technical and moral.

The simple fact is that code quality tends to improve as you move between platforms... non-obvious bugs on Windows become VERY obvious in the Linux port and vice versa, and thus get fixed. So even the Windows gamers will win in all of this.
