This has probably been discussed a lot but I recommend multiplayer. The thing is Rimworld is almost my dream game. The colony management along with the attacking aspect is everything I could ask for. But it is missing one thing... Multiplayer. It would make the game so much more interesting. Letting players go up against each other with their colony's. I feel like it would make trading much more interesting along with raiding, defending against raids, etc, etc. You could set up a way to set up dedicated servers for your game. Use TF2's custom game system. You have base dedicated servers that get wiped like every few months to keep it interesting. People can host their own dedicated servers or just have a server open as long as they are on. I would say that on a server your colony doesn't carry as to avoid confusion. In multiplayer games AI should still be enabled that way you will never be definitely safe. I know it is a lot to ask but seeing this added to the game would bring me and a lot of others joy and also the interest of so many more possible players.
