Procedurally generated stories. Each play-through generates you a new character. Their gender, appearance, sins, desires, regrets and torments are predetermined and out of your control. You must progress through the environment and find whatever it is you desire, progress enough and the character following in your footsteps may share a solemn moment by your grave.
(story text is generated each time a play through begins, you will never see the same story on a grave twice. gender, appearance, sins, torments, desires & regrets are not your choice, you must accept who you are and make of it what you can.)
