Many people are frustrated for want of a better term with Linux because they think it is lacking in the Games department, all said and done this is not an accurate assessment.
However it is false to say that Linux games are in anyway inferior to that of games written for the Windows platform. It is also false to say that Linux games are graphically less acceptable or exciting than it's Windows counterpart. Linux supports a rich variety of games covering the basic Tetris and familiar card games to the highly complex strategy and shoot em up games.
It is equally true for both Linux and Windows that performance improvements can be gained as with any game by the purchase of high end hardware, CPU, Memory and Graphics card. Many gamers conduct a lot of research to find the right equipment to use with their many different games.
