Some days ago, the Descent games got removed from GOG.com. Fortunately – due to their DRM-free policy – you can still keep your game and continue playing it. But it will be impossible to buy a new copy until the legal/license issues that lead to the removal are resolved. And of course I hope that this will happen soon.
Of course for the time being I removed the link to Descent 1 & 2 on the Game Content page.
Right now it’s not clear if the games will also be removed from Steam or not as the details of the issue are unclear. But as stated above, let’s hope that the problem will be resolved rather sooner than later.
