I'm so far removed from Blair's one-hour dungeon experiment it's not funny. A megadungeon level takes me 8-12 hours, and then I spend hours more moving maps to CC2. The dungeon maps aren't that bad to do in CC2, just a few extra hours and it's done. The city map is a total chore though. I've got a few shortcuts I can do to get buildings down quicker, but it's still pretty painful.
The JPEG save function in CC2 continues to underwhelm. Fortunately the vector output is fantastic and it prints out beautifully. Here's the work-in-progress. As usual, click to enlarge. If you want to see the hand-drawn original, click here.
