A blog post by Robert Briscoe announces the Dear Esther developer is returning to AAA development by joining Valve Software after a stint as an indie that followed his earlier days at DICE (thanks Gamasutra). Here's word, which does not provide any clues about what he will be working on:

So I’ve decided I need a break from the solitary life I’ve been living these past years. I think I need to be around people for a while; A lot of my energy and enthusiasm comes from being in the presence of people, sharing different ideas, methods and techniques, different views, outlooks and inspirations, and mostly by just being out of my comfort zone (which I have very much slipped into).

Over the past 11 months I’ve been in the process of applying for a US work visa, which was successfully approved a couple of months ago, and consequently, as of March 20th,I will taking a break from indie development and moving to Seattle to spend some time working on cool stuff with a company I’ve long since admired: Valve Software.

So what does this mean for DE Unity? The bulk of the port is done, with just some backend and scripting stuff remaining, so I should be easily able to finish things off in my spare time, plus I have the team of talented people at TCR to help me along the way if needed. So things will very much carry on as normal with that.

As for my indie endeavours? I still have things I want to do in the future, both independently and with TCR, so I know I’ll come back to it again someday, and have no doubt I will be still tinkering with stuff on the side for some time… but for now I think I just need a change… to make hats… cuz that’s what Valve do these days right? ;)
