Spore

One popular game that allows the player to create their own creatures and guide them through the process of evolution. First starting out as a single cellar being which then sets foot onto land which, if lucky, grows into a tribe that could eventurally lead to forming a civilization to finally exploring the vast reaches of outer space. With new expansion, parts, and rumored "X" packs coming soon, it will be interesting to see where this games goes as far as the possiblities. Are they endless?
