Mininosta is one of the favorite maps, but in my opinion, it takes even longer than 8mm6a, due to the larger number of treasure locations (and, unlike 8mm6a, you always know exactly where to run and find them). Consequently, even if your opponent rushes you through the center, you can calmly retreat to your corner treasure locations with control, which I always found in any game on Mininosta, and calmly run around. The average game duration, based on my experience, is 4-5 weeks+.
