So far one expansion available: Severn Gorge. I thinking this "system" has some potential and I plan to do possibly a lot more expansions/variants. Hoping to get some more feedback before I blunder along blindly ahead... Stuff like reviews, session reports, game lengths, imbalances, tweaks, major flaws, cool ideas, etc. Currently researching 1920's + Florida as next expansion. Unfortunately all the books I'm finding on early FL industry cost $20-$30. Working myself up to blowing $100 on the Topic. Got another 7 variants in mind as well. Thinking of rules for importing as well as exporting.
