Hello ! Some wild ideas about alternate maps. I am sure that other players would have some more :
There is a special neutral caracter on the map, which is a cop. It can't be killed, but blocks the way. However, both players can move it 6 tiles max (number to be adjusted), but only in streets or places they have visited. Doing so costs one thug or urchin (we play the thug/urchin on the cop, and then cop can be moved. In terms of role play it follows ans tries to catch the thug/urchin).
If we send the cop to a building filled with urchins (1 for the opponent, or full for us), we earn a victory point. But the building becomes unvisited + gets regular cop similar to an estate.
Similar to the big map, but the turn after a street has been explored it is covered with smog : the caracters there are unidentified and buildings become grey again (but don't regenerate loots).
Great fire of london : (ok, I know, it is 200 years too early...)
The city is on fire, but it also creates great loot opportunities.
The fire progresses every turn ( it spreads from building to building, and can jump across the street). Thus the game area shrinks. But it is possible to collect water in some places to extinguish a building catching fire. (A building is in "catching fire" status for 1 turn and can still produce or be looted, then it is burning)
Some buildings, when cacthing fire can be colonized by 1 urchin. They need to be colonized for 2 turns to give a victory point (and thus need to be estinguished, to not go from "catching fire" to burning )
What do you think of it ?
