What if we could disable some worlds.

How about we just get all control of all townies? Let us build the townies and Maxis no longer generate any type of townies. Instead of taking away options to all worlds, why not let players (some day) build their own townies and who can travel where. This would be a themed world, where you control it all, who comes, who goes, and what they look like, how they dress and who they are (traits included etc.) Yes, players would have a lot of work, but I would rather do all that than the game generate one townie, anywhere. Your themes could expand all worlds, and you control who gets a phone, who doesn't, who does anything at all. Themed play is my answer.
