La Mulana for sure! It’s a game where you play as professor Lemeza Kosugi (i.e. Japanese Indiana Jones) exploring an ancient temple. I admit that I did not have the patience for it. The map is huge and exploration is very non-linear. You also have to solve fairly obscure puzzles. If you really wanted to give it a go, I’d keep hand-written or typed notes separate from the in-game notes. They only let you save so much data at once, and you need more. I still kind of loved exploring the maps even partially though.
