Spore: The definitive game of 2007 [estimated] will allow you to create your own creatures, society, buildings, vehicles, and even planets.
What we are going to be focusing on is: CREATURES
Think up your own creature, describe it's features and personality, along with a picture if you happen to be a good artist [any medium of your choice] and with pertanint statistics such as Height, Weight, Land Speed, and so on.
And to get the ball rolling...
My creature will be based around speed and offense. Obviously, a predator to maintain enough energy for metabolic functioning.
Bipedal for maximum acceleration and manuvering, along with legs of a to be determined ratio of legs to body size for maximum speed.
The head will be high up with both forwards and rear facing eyes for maximum situational awareness.
It will have four arms, two large arms in the front for doing whatever needs to be done, and two extremely long arms in the back with spear like ends for defense against supposed 'predators'.
Height: 3 Meters
Weight: ~200 kilos
Top Speed: 150 mph
Burst speed: 190
Acceleration: 50 Gs [50 * 9.8M/s]
