>you can only do a few things before you run out of energy and need to harrass your friends or wait 24 hours

This is a theme that exists throughout most Zynga games.

The difference I think is that in a sandbox game doing a handful of things every eight hours or so can feel fairly satisfying but in an adventure game there's a sort of story and you're interrupting it after you're just getting started.
