For power to maintain all those along with barracks, warehouses, crafting rooms, etc.I run about the equivalent of 9 of the power production rooms (each 3 room wide.) I actually have more than that but, they're only 2 room wide for a bunch of them cuz i use the remaining 2 block wide slot for power rooms all way up n down along left wall in conjunction with the other production rooms.kind of hard to describe exactly.

I run a vault with about 140 dwellers (currently) and can keep food / water production maxed with 3 sets of cafeterias (each are 3 rooms wide) and same for water production. How do I come to this conclusion? Cuz there's a mod that removes that limit and people have reported this to be the issue when going much above 200.ĪS to the max # of rooms.

That's the only reason I know of for them making this limit. The game starts taking too much of a performance hit when you go over 200 dwellers. Originally posted by snooze:why it have a room limit? for what is all that place when i can never fill it?
