I wonder if you could add to the u7 engine new features like multimap (like U6), bigger shapes (the dragons seem very little) or more shapes for the same creature (also like Ultima 6 and the silver serpents), a bigger map with more superchunks...
I always though that this limitations make things like the centipede or the silver serpent creatures and the multilevel dungeons dissapear from the game
this things would be great for the exult studio and for people who wants to make new games or expansions using exult
