Of course such heretical considerations as ease of use and actual playability never entered my mind, and nor shall they! Why should I let the fact I have absolutely nowhere to store this thing get in the way of summoning it into existence? It is the act of creation that is the point; I can, so I WILL!!!
Anyway, the levels clip together so they can be removed in any way a player sees fit, so I imagine it’s quite playable. It could also serve as the entire battlefield if one wanted to do a room-by-room clearing mission or haunted house style zombie blaster round, with each level separated on the table. And if nowt else, it’s a hell of a LOS blocker!
