Dwarf fortress,
http://www.bay12games.com/dwarves/
Game where you can kill animal x and make for example shirt from its leather, earrings from its bones, food from its fat, food from its meat and throw useless chunks into magma. :P
Not to mention what you can do with metals and how complex metal system it has.
