I remember when CZ first came out, and I was thinking to myself that it could have been awesome, but they f*cked it up with that stupid tactical shield xD. I installed it yesterday (you must switch to beta to see it) and played through the single-player missions. I don't know if it's just nostalgia, but the thing is still fun as hell.
Too bad most of the new titles are FPS, a genre which was rather healthy on Linux before.
Playing Need for Speed using wine, I am still waiting for a first-class racing game...
To put it in another context for you, if a library had a fantasy section but all it had were variations on the Wizard of Oz would you consider that fantasy section to be healthy? This is not to say I don't understand wanting the other genres of games to develop, but the FPS genre on linux is far from healthy.
I agree that racing is probably the worst genre in term of choice on Linux nowadays
