To be honest, I find it a mistake to limit the RP that much in the locale. Tatooine is a pretty boring planet and I'd see the issue that, in like 100 posts or so, we will run out of things to do. Limiting the RP certainly does make sense, but it does need to be a bit of a bigger area, say, the Outer Rim.

Just look at that map, that's what Star Wars is about, isn't it?
