I visited Obsidian Entertainment a couple of weeks ago for the reveal of the studio's first game for new owner Microsoft. If you remember, The Outer Worlds was published by Private Division, Take-Two's label for partnering with independent studios (Obsidian was independent when the deal was made). This was, then, a significant moment.
The game itself was a bit of an anti-climax - Grounded, a small-team survival game with a Honey I Shrunk the Kids hook - but I still got an opportunity to nose around the studio and see what changed post-acquisition and since I visited in August 2017.
The answer, in a nutshell, is "not a lot", which is encouraging. Obsidian still resides in the same office block in the eerily perfect city of Irvine, California, and still occupies the same amount of office space. It's still a bit tatty, which I like, and the only real sign there's now Microsoft money behind the studio is a pile of boxes with computers and monitors in them.
