However, each plant the seedling takes over may radically change the game. And there are other things in the garden of Earth. Animals, insects, poisons, tools, and people that may hinder the spread of your plants, or unwittingly help. The scientist with the most points and the end is the winner and shall be proclaimed Overseer of the new Earth. Set number one will be "American Wildflowers".
