I am surprised that jungle adventures is the only pack to be released with so much exploration. I mean, ruins can be explored, but sims have to disable traps, solves puzzles, fight skeletons, and use adventure gear to combat various mechanisms. Sims can find treasure chests and do all kinds of things. There is no other world like this. Most features involve rabbitholes and interactive shells. It would be nice to see another adventure pack with lots of exploration. I would like to see an explorable underwater region (maybe via submarine), a mountain or cavern, or another cultural themed pack with ruins.
