Was thinking that a game might be more a mix of Polo and Grayhound racing....... Mounted Fubarnii going after a "bunny" thing. This would be a mix of Survival and Warfare training and Sport. A game/sport played in a hollow area.
Survival skills against a bunny! Reminds me of the Klingon Tribble hunt jokes from Star Trek!
Good idea if you scale it up a bit though. A popular 'sport' around the middle ages for nobles was deer and boar hunting. Deer hunting was done from horseback with spears and tested a riders skill and agility, running deer are fast and change direction! Boar hunting was done on foot and was pretty dangerous, the Boars were vicious and fought back!
Maybe a mounted Grishak hunt might be the way to go after all?
In some post I read that engineers make a sort of a competition with their creations. Why not a sport with engineerr's creations?
I think this has been sort of done by the Pax Limpopo "Pig Tickler" rules, played it once, hilarious!
