Maybe, but as someone who spent a summer school breaks worth of time in 2002 getting drivers for a Nvidia GeForce 2 card to run under Mandrake (oh the kernel panics...) to play counter-strike 1.X on wine... It's come a long fucking way.

I use Debian for everyday work and on my private machine nowadays and struggle with the shitty experience of windows when helping someone out now and then. Granted, I don't have much time for games these days, and often fire up the PS for that, but I feel experience can vary as long as you know what you want and manage expectations.
