While gaming on Linux has suffered some recent setbacks with id Software and Atari seemingly having abandoned the Linux platform, there are some bright spots on the horizon. (See Commercial Gaming, Coming Soon to Linux?.)
Many believe that Wine and other Windows emulation solutions may be their only recourse for high-quality gaming enjoyment. That, however, it not entirely true. There are plenty of smaller, independent gaming houses developing and releasing premium commercial games for Linux alongside Mac and Windows offerings. Search hard enough and you’ll find games ranging from low-resource puzzle solvers to 3D first-person shooters.
