I finished downloading MM 4.1. Nice new terrain and features for my Africa map, and for my planned Oceania map. I can't say more about it yet, because I am quite busy for my job and I first want to finish a running game in version 4.0.1. This also means that I won't be able to find any bugs or imbalancies for the coming weeks/months. Lunarmongoose, I thus recommend you to play a couple of games by yourself before you start your work to improve the AI.
