Save File Bug Work Around
When I start a new game, I want to be able to select which worlds will be added or populated. If I can have a save file with five worlds only, then my game won't bloat and create Save file problems.
For example, if I'm making a northern England, spell-caster fantasy world, I won't want Oasis Springs, StrangerVille, Sulani, Chestnut Ridge, Tomarang, Ciudad Enamorada, San Myshuno, etc.
For a spell-caster fantasy world, I'm just going to want at most Newcrest, Magnolia Promenade, Windenburg, Forgotten Hollow, Brindleton Bay, Glimmerbrook, Henford-on-Bagley, Moonwood Mill, Ravenwood, Nordhaven, and Innisgreen. Worlds that fit the theme.
If I want to make a fantasy sea world then I'd only want Sulani, Tartosa, and maybe other worlds with the most water.
If I want a modern Japanese world, I'd want San Myshuno, Mt. Komorebi, and maybe a nearby Tomarang.
If I wanted a USA western world, I'd just want Chestnut Ridge, Del Sol Valley, and Oasis Springs.
I want to be able to grey out some worlds so that they won't be populated and won't add more data to the save file. And later on, if I want to turn a world on or off, I'd like to be able to add or remove a world.
