Hey, this  is really cool, I thought of MB at sea but never of boat racing

Thanks! I enjoy building minigames, so stuff like this is always fun for me to work on.


That's awesome! I've been thinking about a Mork Borg in space and the barges would fit an adventure of that type perfectly! Amazing system.

100% feel free to borrow and adapt the barge rules if you like them.

They're a little oriented around racing right now, but I think they could handle additions for cargo space, onboard weapons, and subsystems pretty easily.
