I know that spending free time around the home base was always a feature of early 'megadungeon' campaigns in the 70ies, but
1. Where does the term 'downtime' come from in RPGs (which was the first RPG to use it this way?)
2. Which was the first modern RPG which used structured procedures for that, even if with a different term?
To my best knowledge the answers are:
1. Ghost Lines (2012?)
2. Mouse Guard RPG (2008) with 'player turn'
But Im sure Im wrong! Please correct me if you can!
