New merchat system + global market ideas

How about making the merct system a bit more rewarding w gold and silver like npc comingo to your base for sell u stuff may be particular resourves or even weapongs

Or if u want to have even more fun a global market selling explosive or any material that players can sell and buy like any mmo multiplayer has, au can have carrie trhalls and send them to cities to buy certain stuff the bigger the lvl the better the prices(?)
