You go into a giant tree and kill the last of your kind. Then you off yourself and save mankind!
You destroy the reapers, also you die and leave your loved one alone and lonely for the rest of their lives.
You destroy the last defense for an evil ambassador only for your father to die because of getting crushed by a truck and you avenge him by pushing the guy down a volcano only for your best friend to become the new King of Spargus
There is no end. You just keep on mining and crafting.
