Some good proposals that look like a richness of play in 2020 is on the cards :-). I would like to start to break into Battlegroup this year, so will be interested in any write-ups that you do here.
This is a long slow burn project, as I am very slow to paint my miniatures, and I am relying on another player and getting the free time to align so we can play a game.
But, I will post here on Battlegroup when I have something to post.
I love these rules, but we found it is a set you really need to build all of your forces before playing, rather than get units here and there and play with what you have at the time.
