Try being in the middle of a space ship more or less by yourself, or only with a droid and it certainly can have the sense of very small. Particularly places near asteroid belts, black holes, or other really major events like that, but more or less I'm used to it. It's where I grew up after all. Not everywhere is like Coruscant though - Coruscant is unique even in our galaxy. Most planets or more like this one - there's a mixture of inhabited places with woodlands, oceans, deserts, and so forth. Kashyyk is entirely forest, for instance while some place like Tatooine is primarily desert and a lot more rural.
I've been to a lot of them. Before the Republic I worked for the Emperor directly and he sent me to a lot of worlds to check up on things that he could not do himself.
I understand that. If you'd like to get out I'm more than happy to show you around. I've been here for several months now and I feel pretty good about my ability to navigate New York City.
