Fair warning, this is a very big game. With a 2-4 hour play time and quite a few nuanced rules to comprehend, using this game in a classroom will represent a serious investment. The return on that investment is also quite high. Dominant Species is an incredible simulation of evolution and species interactions. Published by noted wargame company GMT Games, this game pushes players to think both tactically and strategically as they develop their species in reaction to the changing environment. One must carefully consider available land types, food sources, competition, and potential events in this comprehensive game. Works beautifully in AP Biology courses with a richness of detail and vocabulary that can support more in depth research and consideration by advanced students.
