Jungle Adventure was probably the first pack I bought, only one I paid full price for, and have no regrets. I've always played it single sim, the thought of trying to keep multiple sims under control kind of scares me. Use to explore the whole jungle in a single go with supplies for the needs or reward traits that dampen the needs, but recently I've been having more fun taking several days to do it all with some time spent back at the rental to build skills to make the traps a bit less deadly. Occasionally I'll speed run it with a sim that has all their needs dampened and appropriate skills maxed.
