Wow, I already had an account here. Anyway, having outside individuals is a good feature. Why you say, well.... There are numerous uses for them, from repair teams, perhaps deployable from tube airlocks which could themselves perhaps be placeable or defaultly spread out, or from some sort of emergency vehichle. Imagine also infiltration teams and the like, also deployable from vehicle. Unless youre in a remarkably hostile enviroment I imagine individuals would take strolls from time to time, the university crew in particular, to collect rocks and inspect buildings etc. There are many potentially usefull applications for this particular feature, it is however mostly a fluff idea, quite nice to see in game but not a requirement..... then again the game itself isnt required for anything.... hmmmm -drones-
