Some mainstream gaming channels on youtube are already half recommending linux except for online games. Really doubt microsoft would have the balls to try something like that now
curious, i wonder why not online games? i play a few online games on linux just fine. they are not the newest ones, but that's the thing, any older games work, online or not, and only some of the newest don't, and that's only because wine/codeweaver/valve didn't get around to implement the fixes for wine for those games yet.
microsoft doesn't need courage, they just need a few leaders dumb enough to try again.
