I love the science behind this, and it can even be used to model real life: Humans packed too closely or far away from each-other are bound to die. Or, if you believe humans can survive none-the-less, Mycelium follows rules similar to this, it's really fascinating!

I know right? I like this game more than The Elder Scrolls and minecraft! Can't say it's better than Borderlands, but the two are definitely close... my girlfriend still takes 1st though.
