Great idea, but how are you able to store multiple 3x3+ battlefields?
I will have them set up for the next 1-3 months, or how ever long the campaign lasts.
I have a (roughly) 17' x 21' game room where I can leave thing set up for an extended time. I usually have 3 tables in operation, which allows us to split up the gaming group into smaller groups, so no more then 3 players need to be on the same gaming table.
The main table is 5' x 9', that will have the social club, skid row and the downtown core (about 5-6 layouts).
A secondary table (currently set up with Chinatown) that is 4 1/2' x 5'. (maybe 2-3 layouts)
A third table (the airport) that is 3' x 4 1/2'.
In addition I have added an extension to the main table that is roughly 2 1/2' x 4 1/2' which will hold the docks and warehouses. (2 layouts, one blending in with the edge of skid row)
I play kind of loose and fast with the whole 3' x 3' concept, I keep it close to that size. The idea is to build a setup that will allow overlapping 3' x 3' layouts. So obviously players will not play two different scenarios side by side as, for instance Little Italy borders Chinatown, so a game in Little Italy means the 3' x 3' layout will overlap the back alley of Chinatown.
I did not build any 'battle boards' so Nothing is permanent. I laid out some roofing paper as a base, that then gets painted up (like the airport table) or has cobblestone road placed over top. In theory I can roll up the mats when done and store them in the garage.
Now storing the 50+ buildings that I have, that will be a challenge...
