Hello! I'm not really that experienced, but I have used Source Development Kit, Fallout's G.E.C.K, Skyrim's Creation Kit and Project Zomboid's Mapping Tools in the past to work on buildings, terrain, object placement and more. I'm a huge fan of pirate games, and would love help you make Hearts of Oak into a great game. I don't have any experience with Unity sadly, so I understand if you can't really use my help for anything.
