Called Spore.. still in development by Maxis (sim city/the sims people) - they know there stuff

watched this vid on google, its a good 30 mins long but the game looks friggin awesome!!!

Google link

bit of a step up from them tamagochi things.

That does look mighty impressive

I like the changes in scale as you progress through the game (from microscopic to galaxy level)

If you play the evolution right you may be able to evole your race into monkeys and have them walk around with guns
