Pretty hilarious if after years of being the scourge of Linux and FOSS advocates, complaining how they could never leave Windows because they need it to play, gamers become our greatest allies, switching in droves to get more out of their hardware and games.

Really, this isn’t entirely new, I remember some games were known to run better on Wine than Windows years ago already (Soldier of Fortune comes to mind).
