I just got finished with beating Riven for the first time. I adored the way the game seeped into my real life with pages of notes about the world I was discovering. Are there any other games that can match this feeling? That really work best when you have a journal in hand?
My most recent such games were Her Story and Return of the Obra Dinn.
During Her Story I ended up with an A5 sheet full of keyword ideas I wanted to search the recordings for.
Obra Dinn had me draw multiple iterations of a ship deck while trying to figure out who was likely to sleep in which hammock :D
