The deals were made official at Microsoft's X018 today, with the rumoured purchase of Obsidian Entertainment, developers of Fallout: New Vegas, along with RPG developer inXile Entertainment now being brought into the Microsoft fold.
Obsidian are known, in addition to New Vegas, for titles including Pillars of Eternity and Kights of the Old Republic 2, with inXile being responsible for such titles as Wasteland 2, Torment: Tides of Numenera and The Bards Tale series.
It's been a big year for Microsoft when it comes to studio acquisitions, with Ninja Theory, Playground Games, Undead Labs and Compulsion Games already being brought into the fold this year, along with existing studios like Mojang already being part of the Microsoft family.
Corporate VP of Microsoft Studios, Matt Booty, said the studios would continue to operate as autonomous units, although no doubt limited to PC and Xbox One, and that they would still focus on RPG experiences.
Microsoft have also stated a commitment to improving their PC gaming offering, with the rumoured purchase of Obsidian being one example of this, and the staff and IP of both studios will be retained and continued to be developed.
So potentially bad news for PS4 players who enjoy any IPs from either of these two studios, but with any luck they will otherwise continue business as usual, albeit with a focus exclusively on Microsoft platforms.
