I agree that Linux users can also be a pain to deal with :)
But yea from my experience the game market is a little different because there is a growing group of people that rather would not boot Windows for gaming and instead stay on their platform. This group of people is very thankful for ported games.
What I heard third hand from game developers has been that it’s fairly hard to get games to perform well on Linux, and that most of the complaints come because of performance reasons outside the developers’ control.
