Yes, that game is just great. Now I have to :
think about my defense play and defense tweaking
create good game markers
train, and train again ^^
I'll certainly have new questions. Playing the game, I thought about a lot of things : space between the players, linemen pivots, stacking, game sequence, play developement duration, kicking, etc...
EDIT : BTW, we used "base front tackle" rule, and enjoyed this rule for the good running games opportunities it brings us.
Actually, I'm also reading other "advanced" rulesets to see what we should prefer to play. I like the Buzzball ruleset (except for the tackling rule), as soon as I'll have a timer, I'll try it. In my humble opinion and own taste, I like rules who doesn't allow stacking/piles.
