An educational boardgame on the future of Earth's environment and the destiny of life in the next 100 years (from the box cover). Players compete to have the most points but moving through a spiral of eco-impacts after rolling a dice. These eco-impacts have either positive or negative impacts on the environment and the events all relate to one of ten environmental impact areas (land, population, climate, politics, energy, water etc). The advanced game adds secondary impacts and eco-events (again both positive and negative) to the game taking it away from just a straight game of chance. Players get positive or negative points when double positive or negative events happen in the related environmental impact areas. The level of detail about possible future environmental events makes this game's theme very strong and probably its strongest point. It is great to read the 260 eco-event cards and consider if they have already happened or are still likely to since the game was published in 1993
