That looks EXCELLENT!
I really like the lay-out, and I love how it will mesh with the other Transit maps without looking like it's too much of the same. Very well done. I like how this one is sort of a polar opposite of the Cargo Docks. That one is very cramped and Melee friendly, this one is a bit more open.
You're certainly right, with all the doors blown, there's some interesting firing lanes. But to be honest, I'm not sure they are THAT bad. On first glance, I would say this might be a great map for the Restricted list simply to give shooter squads somewhat of an option, especially if you also include Cargo Docks for the Restricted list. Sure there's some nasty lanes, but gambit is still pretty well contained, and there are places on both sides where you can hide nearby but completely out of LOS, or possibly even hide within gambit and still be somewhat protected.
I like how you re-used the ship in the upper left hand corner. That's the one on your Dagobah tile as well, isn't it?
Again, completely disregarding miniatures play on this map, I am SUPER psyched to run an RPG scenario using these 3 maps. That's going to be epic. And in fact, if you make your PCs start on, say, the Cargo Docks map, then work their way through Freight Transit Station and Offworld Shipping Center, then you could end with the Transport Facility, and probably actually not need 2 copies of the map to pull it off. Just wait till your PCs have all moved off that map, and then move it to the other end of the long row of maps.
Still, I'll probably order 2 just to be safe. I still need to get the Swamp Caves map though too, so looks like I need to place an order here soon!
