Excellent thread IK, and as someone who loves to overanalyze things for fun I went to work as soon as I saw the topic.
I've come up with one about everyone's [including mine] crack Minecraft. This game is a Darwinist game because it shows humanity evolving to survive the hostile wasteland that you have been placed in. Everytime you die your kin, aka your respawn, has learned something new about the world and you strive to bring it under control. You work during the day clearing forests and stripmining acres of land that various wildlife inhabits.
Why does your character do this? To survive and adapt to make him the greatest hunter of them all. Soon you have armour and a fortress, traps and barricades to hold off your enemies as you strike them down, taking what you want and need and converting it into your own little empire. Soon though this isn't enough to just have your basic necessities, you want conviences, buildings you create because you can, thus the wastefullness of humanity comes to full power as people create models, statues, fortresses with no purpose but to show that they are the true master of their destinies.
Just a short little blob I had fun with; thanks again for a fun topic to work with.
