A current map in the Draft stage of the Foundry (Conquer Mart) made me think of a Mall map.
It would be rather similar, but I think a Mall is more conducive to CC gameplay than the bird's-eye-view of a single supermarket.
The map would be a cross-section of a 3 story mall. Stores would attack adjacent stores, but you would have to use the escalator or elevator to go up and down between levels.
There could be a Food Court, Ice Rink, etc.
Maybe mall cops?
Hoping to get some initial feedback before I make a first draft.
