Would Las Vegas work as a map?
If done properly, it could be a beautiful map with interesting gameplay. My two concerns are:
1. It may fall into the Japan trap - the strip has a very linear design.
This could be combatted with the monorail and strip itself. The strip would be a no-man's land where you lose armies in the desert heat, but could make travel quick. There are also back roads that could make things more circular.
2. Are we allowed to use hotel names?
I haven't drawn anything yet, but here's an idea of the shape of Las Vegas. This map is something like what I'm thinking of.
