Sure, if you want, at least Tulga is free for use. And yeah, if you wanna give credit, go on. At least it makes the readme look longer and cooler.
There seems to be a whole lot of problems with many scenes though, as the .711 rooms seem to be different than the old ones. Don't know about that really, but it seems that most of the objects are in strange places and merchants be inside battlements 'n stuff. And Sargoth castle is very different than the old one.
So if my city (Tulga) requires any editing to match the new rooms, feel free to do it yourself or tell me to and I'll do.
