Dense and flavorful, this is a game about composing a poem for a person you have just killed on the road. And also you are the kind of highwayman that people romanticize in poetry.
It's very cleanly designed, the layout is excellent, and the illustrations fit in perfectly with the subject and tone.
The bulk of the game is just writing lines of poetry, and there's an optional challenge mode that allows you to randomize restrictions like rhyme scheme and meter, but at the end of the day if you really don't want to write poetry, playing this game is probably not for you.
Reading it, however, might still be. The game is clear and direct with its rules, but whenever it gets the chance to do fluff, it unleashes with some extremely genre appropriate not-quite-verse-but-I'd-struggle-to-figure-out-what-else-to-call-it.
Gentleman Bandit is a joy to read, and also viable as a party game (although admittedly it's the kind of party where someone writes the first draft of Frankenstein.)
If you write poetry or have who friends do, or if you want some material to get you in character for your next weird west or hellfire western game, I'd encourage picking this up.
