Not him but the no games argument is not true anymore. Windows is the best os for gaming mostly due to most game developers are trained into developing for it with microsoft's closed APIs, so the simple process of porting a game that was developed for windows to any other platform will affect negatively the performance of the game. This with the fact that the marketshare is small compared to windows there's hardly an incentive at the moment to optimize for linux, making look as if the platform were worse for games than windows when in fact to flip the situation you'll need to change the idiosyncrasies on the industry itself.
The fact though is that the situation on linux is not nearly the same than two years ago and now those who prefer linux over windows now can play games on it, helping to break the vicious circle, but still there's a lot of things to do for linux to compete in the gaming side. I anyone wants for this to change i recommend to play the games you can on linux when possible and ask for linux ports.
I notice some people doesn't want's for this to happen but if that the case let me ask (not directed specifically to the person i'm replying): how are any of you benefited in a meaningful way with the current situation? because i consider that keeping the statu quo just to have a tool to win an argument on what OS is better is not a meaningful thing. how having less options and practically being locked to MS products benefits you?
