fyi â.â is the key for skipping dialogue in all the LucasArts adventure games from the 90s, which are like the foundational works in this genre, so I would say itâs incorrect to call it âweirdly chosenâ; it is in fact a pretty widespread genre convention at this pointâŠthat said, itâs understandable that someone who hasnât played all those games wouldnât think of â.â as their first instinct.
But for me (someone who has played tons of old adventure games) it was very intuitive, i.e. I guessed it without even looking at the controls :)
