Over the last weekend, I taught my son how to play Lion Rampant. I picked it up about 5 years ago when Games Workshop blew up Warhammer Fantasy.
It is a fun, simple, medieval skirmish game by Daniel Mersey and published by Osprey.
The rules are streamlined enough so that you can potentially play multiple games in one evening.
I would recommend checking it out.
It can be purchased below at Amazon: https://amzn.to/2RSuwO4
Or from Osprey Directly at : https://ospreypublishing.com/store/osprey-games/osprey-wargames/lion-rampant-medieval-wargaming-rules
