I played Napoleonics in 25MM (MINIFIGS) for thirty years (see Post Waterloo in this present webpage).
It was fun. Specially when we played with my brother and friends when we were young.
Funnily enough we did really make a mess of it (meaning the rules we used) but one day in one of the refights… The Old Guard did put the British to flight and remained in possession of the bloody field of battle at Waterloo!
It was really hard to contemplate a “new” refight after that.
By chance in my megalomania I had Austrians and Russians too!… so we moved backwards to Aspern-Essling… LOL
Those were the days. Some are still doing it In the Grand Manner.
