While Linux may not be in the front running of leading games, they are making strides to overcome this. There are many games specific for Linux and many games that can be cross plat formed using Wine and Play on Linux. Granted this takes a little more effort to do than using Windows or the Apple OS.
The one thing that is a definite when it comes to Linux they are innovative and are willing to try new areas of exploring possibilities of computing experience unlike the mainstream operating system.
We have a new game being introduced for Linux where the controller is a headset, and you use your mind to control the game.
MindLabryinth
MindLabyrinth is a game where you control an old mayan avatar and must solve puzzles to reach Patchamama's hidden temple. The game is clearly a retro puzzling but it offers as a bonus a unique support for NeuroSky's MindWave headset - if you own it - to read your brain signals and interpret them. With its retro graphics and old-school mechanisms the game will delight casual as well as old-school gamers. The game itself is linear. You progress through a series of 52 levels of increasing difficulty.
The real fun starts when you use the Mindwave headset, you will have to actually use your brain to make stones move, gears work, etc. The game will even ask you to achieve a meditative state to recover health.
The game will soon be available on Linux desktops including Ubuntu. The company has made available a demo of the game for Linux platform.

Mind Behind Mind Controlled Devices
In 1999 a little girl was playing with the new remote control car that her father had bought her as a birthday present. Her older brother kept taking the remote away from her to play with the toy himself. Frustrated, she went to her father and said “I wish I could just control it with my mind”. Like most fathers, unable to deny their daughters anything, he set to work.
Her Father was Jong Jin Lim, a psychologist. He, along with a neuro scientist and a mathematician, (and later a small team of engineers) created the first Neurosky technology.

Real innovation at its best.
