Machi Koro Legacy
Game
The quickest full campaign on this list: 10 games of roughly 30 to 40 minutes each, so a group could finish it in a few evenings. Along the way you tear up components, add stickers and open surprise envelopes and tuck boxes as the dice-rolling town builder grows new rules.
The payoff is generous. At the end you keep a customized version of Machi Koro that you can go on playing, which takes the sting out of the destruction. Reviews split on the legacy layer itself: Mano Kent Games called it a delight, while Meeple Mountain found few consequences to player choices, so it suits newcomers to Machi Koro and groups wanting a light legacy game more than those after deep consequences.
