Well, i'm sorry. But i am currently working hard on getting the new Battle Depths version out, so i don't have time to post all the info here =(
But yes, i started this from scratch. The only thing that is not my idea is the concept of Hero Arenas.
Edit: That got out wrong.
Ofcourse i've also been helped by people with alot of stuff, and many people have contributed with their ideas, but i started the map from scratch, and did most of the work myself.
