Thanks for reviewing Shadow Over Tarkintown! I think your feedback is all very accurate, and a few of those points I actually adjusted while running it myself (though the adventure itself never got those changes incorporated).
The point you make about the map is an interesting one. I'm always torn between maps meant for the GM or maps meant to be used in actual play. Maps for the GM will contain useful labels and indicators so they know what goes where. But having those labels and markers and whatnot on a map means it's not really appropriate to use with the players, since it likely gives away more than they should know when they step on the map. We opted for a "player" map, but that does lead to the issues you describe, meaning it's up to the GM to figure out and/or interpret what the things are on the map and where everything is.
Looking forward to your thoughts on No Safe Haven! It's a lot more ambitious and may answer some of the questions you had surrounding the story line of this one. We always meant to make this a two part adventure, though each part can stand on its own.
