Whenever I try to sell a friend or co-worker on trying to play the game, I usually phrase it thusly:
“Do you like spending four to nineteen hours in a room with a bunch of nerds staring at a thousand tiny plastic pieces sitting on top of some cardboard?”
This could explain why a couple of people in the world prefer other boardgames :P
“Sureman” noted that some powers are less interesting. I don’t feel this way when I play, but I know why some people do. I have an interest in the history of WWII in general, so I wear the rose-tinted glasses of “this is cool as hell”. For a type of player that just wants a game, and gives zero to few shits about the history or theme of that game, being dealt one of the countries might feel like they are having less fun than they would with one of the other countries.
I love the hell out of A&A 1940, but I don’t know if I’d put it in the top 10 board games. It’s a pretty niche kind of thing, and that’s one of the reasons I love it so much.
