The real question is who will have time to play it FTF?
I have AA Classic, Revised, Europe, Pacific, 50, and now 1942 but our group usually has time for Revised now 1942. We’ve played FTF one game of AA 50 41 and 42 scenario but it takes too long to setup and to play.
For AA50 we are now PBF as it’s easier for time but not for making moves as staring at a map program is not a fun thing to do.
So now AAP40 and AAE40 is coming out with bigger boards, assuming new rules, etc, etc, who will have time and space to play it FTF.
Classic was great for casual 5 player game because back then we didn’t know better and played on for fun.
I’m not sure if the game is endangered or the actual FTF games will be. For our group it’s probably FTF games with AA50, AAE40 & AAP40.
