There track record is fine, apart from a near catastrophic error with the xbox one ( which almost took rare with it) the OG xbox the 360, one x and now the series consoles are/were great. They've released some fantastic games.
What great IP have they created in the 20+ years they've been around?
It seems to me even when things start out hot with externally acquired IP like Halo or Gears, as soon as its production moves to an internal team... things don't seem to go from strength to strength
So, again I'm asking what makes you confident that moving to a MS management team is going to maintain or improve quality of output?
This is the crux of the matter if you get past the platform-war bollocks: Is the transfer of ownership going to be beneficial to the work? Or is it going to go the way the EA takeover of Westwood went?
And please, for the Love of God stop pretending that MS are going to give all their acquisitions a free hand to do whatever they like forever, without financial consequence or oversight! The bigger the roster the less painful it becomes to cut underperforming members. Netflix cuts shows all the time, but the so-called "Netflix of gaming" is going to be a creative utopia?!?
Above all else, when a company get absorbed under a giant corporate umbrella, what it means is their fate is no longer their own. They are existentially bound to the good graces of their corporate masters, and that grace can be a very fickle thing. This is why I dislike consolidation.
