A modern successor to M.U.L.E. Yes, I know Offworld Trading Company is supposed to be this, but they really screwed up the end-game. (winning is entirely based on a flawed stock ownership system)
Came here to say M.U.L.E. I always regretted not having a chance to ever play a four-human match. Seems like all the MULE reboots are/were stillborn. I thought the gui for the auction process was quite clever.
