Thanks everybody for all your kind comments. Today I will be doing some of the nitty gritty work, looking into each and every build everyone shared and seeing just how much of this world could be played even without store items. I hate to have it not be playable for all. I'll try to list the places that have a lot of store items. The basic world itself, with all the fantasy landscaping, should be playable and I think, (but not sure), that what I personally built has little or no store stuff.
EDIT: I forgot one builder! Spork-Tastic for her fantastic Topsy Turvey Mini-Mansion. Wild and wacky and I think, no store items.
