Well... That does sound pretty scary indeed. But why such a post on the Tripwire forums of all things?
If you meant to kick up a debate, I'm afraid there's not much to be said as mere gamers. Besides buying games, what else can we do? And even then : that might not be enough, depending on how good a game is selling (or how poorly editors spend their money on)
For Microsoft specifically, I have no crumbs of context, so I'm surely mistaken. But could this come from the large amount of game studios they bought? It felt like they were on a spending frenzy for a little while.
