Well I’ve well expanded out of the A&A universe though it is still a first love. There is a HUGE world of games that we especially as US gamers have overlooked outside of A&A. WWII has a plethora of games out there if you’re willing to explore.
However, in the UK market especially, there are many, many, many games covering even the smallest and largest battles of history varying on complexity.
I would encourage anyone to take a dip in this pool. I actually got my wife to not only play but ask for more of Memoir '44. Sure it’s not A&A but it’s WWII and some day A&A may be “go to” game.
So, while A&A is a favorite, a smaller, weirder, not necessarily A&A game can be the gateway to WWII without “overwhelming” potential a “war game junkie” with the likes of G40 or even AA41.
It seems backwards but more “complicated” games with a smaller scope can really convert people to the thought “well this is really fun, what else have you got?”.
