I don't think I've ever played an adventure game with an accurate portrayal of the Knights Templar other than a brief history in Treasure Hunter.
But if you play RAMA, you can add Base 8 (octal) to your collection.
Funny how the Knights Templar have become so popular in games, books, and movies.
Never played Treasure Hunter or RAMA. Just looked up RAMA: an interesting classic.
I was trying to remember where I ran across the other Base Number systems. Was it in Myst games? Sentinel? The Aura games? Mysterious Journey?
Seems like I had to work with these different numbering systems in a few games.
Also, after playing adventure games, I'd like to think I've gained some rudimentary skill in electrical circuitry, plumbing, and small engine repair ... but I have my doubts.
