This seems questionable. In general the demand for Linux games is less than 1% of the market, and often less than 50 people will buy Linux versions of a game. I’ll say, choosing Linux as a gaming platform just isn’t a great idea, considering very few games exist for it, and the market demand is so low that very few developers will bother to make ports, except for ideological reasons.
If you really want to flog the gnu, some sacrifices have to be made for La Révolution! Otherwise, dual boot Windows.
