Try your hand at evolution with the revolutionary Seventh Cross:
Evolution. Your goal in this RPG or Adventure is to evolve your
character from single-celled organism into the most dominant species on
the planet. You have four different areas of your character to develop:
head, body, legs, and arms. As you gain evolution "points," you can
divvy them up to improve specific areas of your body. You can create an
intelligent creature that relies on its wits for survival, a beast that
uses brute strength to move up the food chain, or a well-balanced animal
that is capable of out-smarting or out-fighting enemies in order to
survive. As you build your character and move up the evolutionary chain,
predators will keep you on your toes as you try to avoid becoming their
next meal. As the object of the game is evolution, there is No "end" to
the game in the traditional sense as there are always new ways to
evolve and grow.
