Journal: Any games developed for Linux?

I just browsed the web in order to find some new games for Linux. (Don't get me wrong, I clearly prefer FreeBSD over Linux for political and practical reasons, but it's Linux emulation does a very good job) My success was mildly speaking demoralising.
So I ask the following questions: Are there any decent games being developed for any free operating system? Do new games only appear on Windows? Is there no chance for companies to earn money with Linux games?
