I am looking for a copy of the game without DRM, as I am not fond of the stuff. From what little I could find with my cruddy google-fu, the game was once on Gamer's Gate, but is no longer being sold there. Physical copies are available, but comes with the TAGES DRM. Does anyone know where a legal DRM-free version is available?

Wouldn't the game's/developer's forums be the best place to look or ask? That's how I determine this stuff. Otherwise you'll be hunting through a DRM master list somewhere and those tend to be incomplete.

Part of the problem is that the developer is Russian. However good their games may be, their websites and forum tend to be on the lacking side, if you can find them. (in my experience thus far) The closest that I have been able to find is the Pirates Ahoy community, but the latest posts on the topic of buying the game only mentions getting the physical DRM copy through Amazon.
