Alot of my family plays those, as do I from time to time.
Okay so you have SimCity (3000 = <3), the Sims, and from the looks of it now Rollercoaster Tycoon (which is indeed a great game)
Have you tried Zoo Tycoon? Spore?
Probably any of the "tycoon" games could serve you well (though I can't vouch for them all)
Myst maybe? That's more of a point-and-click adventure like the Nancy drew series but involves some pretty weird thinking puzzles.
I also highly recommend the Phoenix Wright series on the DS if you're into serious thinking games. Those will definitely keep you on your toes (and it's frickin' hilarious). Hard copies are a pain in the ass to come by though, I could give you a site with a good emulator and ROMs for the games.
The Professor Layton series is also another one for big thinkers but I've never played it myself.
