just putting the idea (back) at there. TiTS has changed... loads and a half since I last played it, with lots of things being added and/or changed.
as for the mechanics, I do have some of that.
to grow stuff players need the Seeds/pods/etc from mobs or merchants of diff planets.
stuff must be tended to: kept watered, maybe add some fertilizer or such
certain NPCs (Crew/Followers) can work on the farm either doing the basic tasks or adding their own special benefit.
