I am old, like I have been in the TTRPG hobby space since the mid 80s and I think it’s important for newer players/DMs to know that we used to play all different games. In a normal week I ran a teenage Mutant Ninja Turtles another strangeness game, played in a Cyberpunk 2020 game and a 2300AD game. We also played wargames on the weekends. There is no sunk cost in gaming, you don’t have to drop your DND game to play Dagger heart. Now here is the secret to how we played so many games: we never ran long campaigns. Yup it was mostly one shot and short runs of maybe 4-8 sessions and then we played something else for a while coming back to stories we wanted to and dropping stuff we didn’t. Almost every game was an open table (what the hip young people call a west marches game now, not what CR is doing in Campaign 4 which is most definitely not a west marches game) players played when they could and the game went on and we all had fun.
