You could encourage trade by making players rely on one another more. (Of course this applies to Multi-player only) Some of the Mods implement a reudementary class system. I'd like to see this expanded on. Perhaps something like this: Classes can include for example Medic, Engineer, Cook, Farmer, Pilot, Soldier, Biologist, Chemical engineer. The player can unlock all the basic crafting recipies, but the more advanced ones require the player to select a class before those recipes becomes available. Players can possibly unlock recipes in closely related classes at a penalty (eg the recipies costs 20x more points in related classes and 500x more points in un-related classes) Perhaps after selecting a speciality, the player can select a second class in which to dabble, eg a Pilot that also likes to cook, can get cooking recipes at 5x the cost. The idea is that all players can still craft the most basic HV or SV with small thrusters, perhaps grow some carots, make a basic shotgun and the ammo for it. But to craft better thrusters, they need to specialise. An Advanced infection could be slowed down by basic medicine that is easy to obtain, forcinf the player to pop pills twice a day until they can find a Medic, but to completely cure the infection requires medicine that only a Medic can craft, made from ingredients that only a Biologist can craft. Of course this sould be optional, for those who don't like it. Or allow a server to let players select up to X number of specialist areas (For servers with small numbers of players) I like the idea of the trade consoles in the game. But on the servers I've played, nobody uses them because everybody has access to make everything themselves.
