Lochlannon

The war game would be an option not change the game. Just a different way to play don’t want to touch the game or change it - just a different way to play.

Bigger boards. Feel the existing boards are sorta cramped sometimes.

Conversion rules to a full Wargame. Same models now a way to bring it to a tabletop. Generic enough to be reused with MBP and future systems. This could be a living rulebook and your existing items would lend itself well.
