Most games use a standard install such as "./armyops.xxx" will install it. The Unreal Tournament 2004 is the same way. All native games I played are like that. Install a gaming on Cedega is easy "cedega blahblah.exe" of course you might have to do some tweaking. Although cedega has never played any games right for me even the ones that it should run with out any tweaking. As for someone starting a company to port games it has already happened. But they went out of business. You can find out some about them here http://www.lokigames.com/. There is another company trying the same. I forget the website. You can try http://www.tuxgames.com/ to buy native ports.
