A great addition to RtR would be Steam Workshop support. I could easily see this game becoming something of a new Dwarf Fortress with 3rd party additions such as Dwarf Therapist. I realize this game is still in early development, but I think certain additions and minor preferences could be added much faster and easier by 3rd party developers. This could streamline the process for the main Dev to get in the bigger, more robust mechanics.
Also first post on this forum!
I realize this suggestion already exists... oops.
