I've seen quite a lot of activity on social media about Dungeon 23, although I've not read the original item that sparked it off. At the moment I'm trying to get back to running games after mental health issues brought some sessions to a crashing halt, but I've been thinking that using one system—in particular a relatively simple one—will help me to concentrate on the game rather than worrying about the rules.

To that end I'm considering a Polar Fudge Adventures swashbuckling Musketeers game. It lacks the detailed fencing rules found elsewhere, but has other elements that I think might work really nicely for a fast moving, light-hearted game in the style of Dumas' novels.

If you go with Polar Fudge Adventures for you game, I'd love to hear how it works out.

You are correct, there are no fencing rules, but it could lean on the Standard Tags (like Vulnerable, Suppressed, Persistent and Area) as described in the sections The Players Did What? section. So for instance a Feint could be an attack that does no damage but makes the target Vulnerable.

Best of Three Contest might be another option. It may be a little too abstract, but I used it play out jousting tournaments successfully.
