Enchancing the station and job goal system would be something. From my viewpoint, I learned the SS13 as game here at Paradise, recently I have been testing some other servers. The thing Paradise has, in comparison to the others, actually is that so-called medium role play. Like, the timespan here is perfect. Not too long shifts for an about-casual gamer to participate from the beginning to the end, nor they are too short, for having room to do some RP. However, the station lacks goals that require work from all hands, goals other than just staying alive with the antag terror and space happening. Such a goal would endorse a bit more RP and co-operation to happen.
Sure a problem here is how to implement the completion check for the goals. I would say the new goals would not be job or departement specific, but issued to the station as whole; like it is now. The work needed to complete those goals should just be bit more dynamic, and the most, to require more people working for the goals.
How about a goal to build a new part to the station? Or a goal to build a new, tiny station or research vessel? These would require the HoP to hire the greytide as low-cost builders, the engineering to see over the work, cargo to supply materials, medical to save the asses of those cheapworkers, robotics to build like new constructor-variants of the Ripley to speed up the building work significantly, some persons from each department to co-ordinate the new ministation's departments, what kind of they are going to be, and so forth. A building goal would, in the other hand, require the completion check done by an admin, or actually, by some on-board person as part of their IC work, like the captain or the RD.
Another one, how about a scientific mission to a gateway world, to acquire certain special items, minerals or lifeforms, which then should be processed by Science somehow?
