My first thought was that Segways would be ideal for the nerdiest fun modern-ish recreation of polo. It turns out that it was a thing.

> The Segway polo world championship is the Woz Challenge Cup. It is named after Steve "Woz" Wozniak, cofounder of Apple Inc., and a player of Segway polo

WhirlyBall[1], which is kind of like pelota + basketball in bumper cars, seems like a pretty good bet. There are only a handful of courts left, but I've done a few offsites at the Seattle one, and it's good fun.

The bumper cars are truly weird - they draw power from the conductive floor of the court, and have a one-handed control system that makes you trigger forward/reverse by turning the steering wheel a full rotation...

Makes me want to dust off mine

There's also e-wheel polo

Nope. The modern version uses motorcycles.

>>Motoball is played in a 5v5 format. There are four players on motorcycles, and one on their feet as the goalkeeper.

I for one wish for mobile crane joust.
