You're an aging millennial. You offer to run an RPG one-shot for some interested friends who have never played. You know you'll have two hours of game time between the kids going to bed at 8pm and energy fading by 10pm. What game/adventure are you bringing?
My vote: Stumpsville for Mausritter. The game has an evocative theme and pitch, a very quick teach, snappy chargen, and Stumpsville is a straightforward, quick adventure that hits all the high notes and leaves open the possibility of future play if people like it.
What about you?
