Probably Sam Mustafa’s rules before he became too enchanted with card mechanics.
That’s just Grande Armee, Might & Reason and Lasalle then. Although each set had little in common with the others in the way of mechanics.
Other than that I’ve never been a fan of ‘families’. I used to use WRG back in the day, but then everyone else did too 🙂
