The droids are cool, and they'll follow you around and can be used to distract people while you're hacking electronics. Changing ranks unlocks new uniforms and galactic credits, which you can spend on parts to build your own lightsabers and R-series or BB-series droids. It doesn't take too long to rise through the ranks of a faction, even with all the breaks to 'sleep' and 'freshen up' (there are no bathrooms or bedrooms on Batuu-maybe Disney told EA they didn't want to see a bunch of videos of Kylo Ren and Rey taking dumps, using the shower, or having woohoo). The missions eventually get a bit repetitive, but there's always a selection available that involve activities like hacking electronics, interacting with other Sims, talking up your faction with the locals, and piloting ships on a mission (more on this in a minute).
