RPG A Day, 2017
Prompt: What is a good RPG to play for sessions of two hours or less?
“None I’d probably like” is the first answer that comes to mind, as my disdain for the hyperfocused “indie” games that are designed to begin and end in a single highly-scripted session is well known. But failing that, something with very light rules and no expectation of a continuing campaign and a rich background… or at least, with a sufficiently well designed “assumed background” that a quick scenario is possible. Again, for me, this goes back to humor games like Teenagers From Outer Space or Toon. Toon is probably better because TFAS relies on implicit genre assumptions that a relatively small subset of players will know well, while Toon’s assumptions have a much broader base.
I’d have a hard time with a serious or semi-serious RPG that was designed to run in two hours. (I’m not considering longer scenarios where you can only play two hours at a stretch; the answer to that is ‘any game, really’. I’m assuming, from the question, that they mean ‘a complete scenario in two hours’.)
