Really sad news, not least due to the below.
shmerl: Too bad. No more DRM-free and Linux games from them most likely.
Obsidian was one of very few established studios I still bought games from. Pillars of Eternity 1 and 2 are very good games. No more of that now, and as a Linux-only gamer who don't use steam at all (nor of course the even worse alternatives), I can probably forget about any of their games in the future -- if they're even worth bothering with now. The quality will probably take a nose-dive anyway.
Still, very sad news. They mostly did things the right way, making interesting games with dedication and love, and supported Linux and DRM Free. All of that dead :-(
