I wasn't planning on using a whole lot of maps for ground layout since I love the fact that this RPG can be played in everyone's minds for the most part.
But when I ran through some friends with the beginner's escape from Teemo the Hutt quick module, I showed my friends the map of Mos Shuuta. When they were ambushed by the storm troopers, I pointed on the map where I felt like that happened.
It happened to be right by the water tower. One of my friends asked if there was a weak point in the structure. I hadn't prepared for that, but I immediately pointed to a light-side destiny point and said "You tell me if there is or not."
He flipped it and sure enough, there was a weak point in the beam which I ranked as a "hard" difficulty shot (with some boosts). He made it, caused one group of stormtroopers to be knocked prone and flushed down the street, while causing a massive distraction to the others because of the panicked crowds. They were able to easily slip away during the commotion.
I love when my players think outside of the box. And I realize that my descriptions of areas may not be enough to always facilitate things like this. Sometimes they need a visual aid to give them more ideas about what to do and things to try.
I definitely will be incorporating more detailed maps and layouts of places in the future.
