Hit 200 today, green bars all around. Think I'm calling it.
This game is a damn *disaster* above 100 or so. Performance was terrible, loading took ages, constant crashes, juttery interface. Just a mess. Game does not scale at all. Especially when coming back from a while away, I'd launch it and then try to move some people around and I'd just get constantly interrupted by births and camera moves to go watch boning and all kind of stuff. Would take several minutes before it got quiet enough to drag someone from one end of the vault to the other. Just try and use that Dweller list to accomplish anything when you have 200 residents. I dare you.
Plus my layout is dumb... didn't realize you could triple-merge rooms until the very end :/ You really need merged rooms in the late game if you're going to have any chance of getting people in optimal rooms and swapping out shifts with a training room crew.
