An amazing module that immediately hooked my players into Nyanzaru and set off a great start to a (hopefully) long campaign. The racing mechanic was simple and much easier to follow than a fully theater-of-the-mind race sequence. I, for one, have always struggled with running chase scenes based on the DMG guidance, but this module helps anchor the idea of such a scene without getting too granular. My players absolutely LOVED forming a rivalry against another group of racers. The "Grung Gang" have now become somewhat of a rival adventuring party that now hassle my players whenever they are back in port.
The combat scene at the end was incredibly well-timed, as my players were itching for some combat after the adrenaline rush of the race scene. I had amped the race up a bit by adding "dark zones" (while passing under a bridge, or through a narrow alley where there were no spectators) where players could use tricks like misty stepping onto a rival's mount and cutting the reins. Still, they wanted more. Thankfully, the authors had my back on that. I'd highly suggest picking up the supplemental map pack, too - adds a lot of visual punch.
Also, little nuances like specifying mechanics for stealing the second prize purse during the post-race chaos were much appreciated. Really felt like all the bases were covered to accomodate just about anything the players chose to do. Will definitely run this again!
