Been working on this my nibelheim re-made in sauerbraten map all night, haven't picked it up to edit for a few months (started it almost a year ago now!).
Has alot of diagonal / off-centered geometry, so far it's looking wicked, there's a screeny of the town from the game for comparison below too. When i've managed to get the basic building layout complete i'll be adding the inside of the buildings (as teleport locations so i can build them on a normal grid).
The greyish map is protonic that i cleaned up earlier (renamed it to protonix), added a few ambient buildings and changed several things.

And some random screeny at the bottom;
