After discussing with some people the above was recommend for him.
My brother is very much interested in miniatures but doesn't have the money nor the patience to paint and build them. So I thought Battleground would be a really great game for him.
Unfortunately he hasn't played it because he finds the fact that the rules are so long intimidating. He is a smart guy but he can't seem to go through the rules.
Is there a summary sheet or maybe a shorter rule set that he could read through that maybe is 5-10 pages and then start playing? Because I really think he will like it once he just gets started but with the rules being so long I don't think it is going to happen.
Worth mentioning that miniature games are inherently complex on the rules front. If he is genuinely struggling with BGFW (which isn't the most complex out there) then this branch of gaming might not be for him...
