I guess it depends on what you're into. People have suggested clubs, sports, jobs... apparently there's even a school if you want to teach or attend classes. [Keith didn't seem all that enthusiastic about the school.] There's also a library, a gym, a shooting range, horse stable... Well, I mean, all of it's labelled on the communicator map.
[He used his own communicator to show Shiro how to bring that up.]
The stuff here's pretty easy to figure out for the day-to-day stuff, especially since it apparently picks up on language preferences. No having to figure out Altean.
