Personally I wouldn't mind seeing drones removed and completely replaced with the Mobile MMI's from /Vg/ station[MoMMI] I'm sure this has probably been brought up before, but looking at the pro's and con's of each, I honestly feel they are more fitting for a medium role-play environment.
Potential Pros
Better equipment for repairing and improving the station
Unlike drones, have to be spawned at round start, and will have a maximum of two on station, unless the roboticist builds more.
Easily perceived when emagged. They get bright red eyes that can't be hidden.
They get different models that are purely cosmetic, and they can wear hats.
Same laws as drones. Meant to improve the station without the crew noticing them.
Potential Cons
Better equipment for repairing and improving the station – some people have issues with machines being able to do similar, or better work than organic crew.
Still a nightmare if emagged. Even those it's blatant obvious when they are rogue, you still have to catch them.
Only way to become one is via starting as one at roundstart, or being a posibrain that's built into one. This removes one of the few ways ghosts can still be involved in rounds.
Cute and fun to see, and for some people, cute and fun is a big NO NO.
