Oh! I like these ideas. When I got bored of day to day life in Sims 3, I would send them exploring in the places from World Adventures, and this sounds a little like it, with new destinations. Puzzles are fun, and I'd love to make treasure hunter sims! It could also bring some new items to already existing collections, too. I also really like the idea of the Genie coming back and the History skill, which could even unlock access to some hidden lots by letting you see trap doors or something. Plus, I like the build assets you're suggesting: ladders and such could be used for so many things.
