brilliant idea for a video series and a great question that’s had me racking my bleary post-nap brains. I did wonder about all those Magnetic Scrolls text adventures? Often brilliant writing and some very clever puzzles, hidden behind a wall of green text and a finicky command parser that responds to most things with “I can’t do that”.
Or, another one might be Captain Blood, an ST point-and-click where you have to learn a symbol-based alien language to play it.
