Recommend adventure/sim/treasure hunt games

[Joeschmoe]

I have trouble finding the type of game that I really like. Can anybody suggest some for me, so I don't have to waste money by guessing? Here are the ones I like best, that I'm looking for more like:

Island castaways
Totem tribe gold

Basically, I like fantasy games with a strong story, emphasis on exploring and solving problems, and treasure hunting. I don't like runners or emphasis on fighting. I do like hidden object games, but only if they last longer than 10 or so hours that most seem to. Ideas?

Oh, I forgot to say that I'm playing on iPad. Thx
