Wonderful poster.
I've never understood Microsoft's disdain for PC gaming. Okay, they have their XBox line of game-consoles, and they want to push that. I totally get that part; Microsoft wants some exclusives for the XBox so that people will chose that platform. But there are a lot of games that just do not work well on consoles (sims, adventure and strategy games, for example) but are a perfect fit for the PC. Yet Microsoft seems to be actively working to sabotage gaming of all sorts on the PC, from killing the MS Flight Sim series, closing Ensemble, and locking games to particular versions of Windows for no reason except marketing. I mean, it's not as if Microsoft has to worry about limited resources; they could have easily supported both platforms.
Windows is still the heart of Microsoft's empire (despite all the money poured into it,it certainly isn't the XBox division, which continues to lose money), and PC gaming was one reason people stuck with Windows; their games didn't run well on the alternatives. Nowadays, Macintosh, Linux and mobile devices are increasing their marketshare, and the PC is only something you use when you have to do work. I don't think it is a coincidence that Microsoft's domination of the desktop began to slip when they made it clear that gaming on the PC was no longer a priority.
So maybe I'm biased but I just don't understand the strategy. They deliberately slaughtered their golden goose - Windows, with 99% control of the home PC market and low cost-of-entry - to chase after the game console market, where they at best would have 50% control and might make a profit after five years.
