Interesting game, btw there were some thing that looked like very weird... For example TumTum didn't capture oil (why?) Or TumTum trying to build refineries on depleted ore node (why?? instead of building refinery on the depleted ore node, it's a lot easier and cheaper to capture the oil derrick, and oil derrick gives more money than a depleted ore...)
Also TumTum could consider to train some dolphins in the late game (especially after Jasper lost his MCV)
