I recently got my hand on an unreasonable amount of styrofoam and was considering building a full table worth of modular labyrinth walls.
But I'm wondering: is there any point of making these for wargames?
Even for TTRPGs, honestly: you only have encounter in one room after another, do you really need to represent the corridors in between?
It's too bad, I already built enough rock formation AND enough scifi buildings to fill an entire table and some more, I don't know what to do with this styrofoam.
