I love this game

This game is highly entertaining and engrossing. It manages to maintain a great bit of scientific accuracy, while still involving the player who acts as a fictional "facilitator" for the advancement of the universe through major epochs. It does a great job of balancing realism with fantasy while acting as a teacher ...
