One of the more interesting parts of this interview:
Quote:UC: Can you give us any details about the internal tools that were created in order to make the levels, artwork, animations, etc.?
JE: The game toolset was actually the game itself. The editor was compiled in with the game. So you would run the game in editor mode where you’d see the maps, the artwork, chunks and so on. You could place objects into the game then hit a key and play it from that location. It was very nice.
Since Crusader and Ultima VIII share the same engine (heavily modified for Crusader, though), I wonder is there a way to run any Crusader game in the "editor mode" and modify worlds. I mean, the HACK MOVER is something that looks like it, but it seems to me that HM was implemented in the game for quick modifying and testing the levels on the fly.
