Ok.. It's time for me to post this... there's a game coming out on June 21, 2016 called No Man's Sky. It's on the PS4 and PC. And I personally believe this game is going to be a game changer literally.
This post could easily be made into a short thesis but I doubt anyone wants to read such a paper on a video game so I'll do a cliff notes version.
No Man's Sky (aka NMS) is a space exploration/survival game that is played within a procedurally crafted universe that is created mainly with the use of procedural methods and algorithms. This math combined w/the Super Formula hypothesis let's the creators of this game basically build a universe w/over 18,446,744,073,709,551,616 planets. Literally 99.9% of the planets will never be discovered, explored or played.
These planets are real sized planets. Each star you see in the sky in the game is a system you can explore and go to if you have the proper ship and resources. Also the planet, animals, fauna and landscape is all built using procedural generation however it is not purely procedural though; there are basic rule systems put in place to make sure things don't look too alien.
Any who, here's a podcast of mine on why I'm so excited for No Man's Sky!
