Greetings, Kashya.

Yes, there was a Kult discussion. However I didn't know about the editor, thanks for telling.
I won't lie: I am sceptic about a 3d program/drawing program weilded into a game editor. 3D Models aren't easy to make and more difficult is to create textures. I seriously doubt the devs are using the editor to create their own.

As for randomly-generated games, I hate to deceive anyone but I've seen some randomness and I didn't like it. Nothing beats hand-made levels or quests.
Ask Sacred players and they'll answer you.

I haven't seen Kult in action so I might be as well wrong, just remember to proceed with caution: if you are buying Kult, wait for a few reviews.
