Disciples III: Reincarnation (Or Rebirth as it's also called.) is now finally available directly on Steam.

Link

It's the updated/remastered version of the game with the expansion included, even required Steam (And it also used a variant of Star-Force but DRM was entirely removed in the previous update.) but due to publishing licenses or what it might have been it could only be bought in retail or via certain other online stores like Gamersgate but now it's accessible directly from Steam.

Would be nice to see a trainer adapted for this version eventually, would have to go through the request process first of course.
(Since it's a new engine and everything it's not just like updating the existing trainer to a patched version as far as I understand how these things work.)
