That possible theme/ focus: Discover University.

I remember people calling Island Living, 'Tropical Paradise'. That's why I won't write off the idea of schools being fleshed out in a patch or the pack itself. I recall the other university expansions adding something to the school systems despite it not being in the name. They overhauled gardening and fishing, so it's not impossible.
I'm really looking forward to the university expansion. It's been a long time coming.
