The enclaves are VERY NICE, in a sandboxy kind of way. They take a little bit of work to get up and running, but they're full of good inspiration and can accommodate a session or three. They're pretty easy to weave into ongoing adventures, too. It's an idea I'd love to see more of, since not every session is Giant Time for me, but it absolutely helps put some monsters into a context with some sites and adventures, and that's really nice.
