I have a game concept for the "2 sessions, 6 hours long, and exactly two weeks bewteen them", and I thought about making the players do something during each of those 14 days (like updating something online every day, or writing something that happened everyday).
Would that be OK, or would that break from the time framework of only 2 sessions that are 6 hours long? Because it's obviously not a part of the session and it takes some amount of time, but it's also not exactly playing the game but more preparing for it, like reading the rules or driving your car to the where the game is played.
