Still hearing 6 mana 88 here <| sep |> If pigs flew out of your ass , I wouldn ' t expect you to live very long . <| sep |> For one , I ' ve devised a way to create a Procedural Tech TreeE 3 DPalL 7 p 5 w . Actually , it ' s a Directed Acyclic Graph that contains manymany effective tech trees . Like lots of procedural methods , it ' s based on a random seed but that can be modified to introduce nonrandom elements , like inheritance of certain attributes from precursor to nextlevel item . Also , the geometric properties of pentominoes can be used to statistically tune what combinations are possible . Which could be done but wouldn ' t be as builtin with a Minecraft style 2 x 2 or 3 x 3 grid . I ' ve also devised some insightful ways of incorporating genetic algorithms which get around the common pitfalls of using those for games .
