thanks for the links, I'm a little ahead of myself as the books are still in the post. I just wanted to get back into mapping. It probably will be based in tatooine. as for the number of player - 4 at the moment. the base will be a little run-down as it is a starting group. I'm going for an abandoned facility look. The previous owner of the facility sold it cheap and in an upcoming adventure the players will find out why. To your other point, yet I am looking for suggestions/criticism as it helps in getting the map finished.
