Well, I am about to play P40 for the first time, but I do know this. I like playing Russia, Italy, Germany, and the UK in Europe - I just like the global game a lot!
The combined 1940 game will not really be comparable with AA50. Like apples and oranges. First of all, the global situation was far different in 1940, of course. AA50 will reign on as the best '41, '42 worldwide game where you can quickly teach people how to play and go at it.
If the combined doesn’t simplify the rules of the individual games, what with all the political situations and extra countries and exceptions and stuff, it will really only reign in the hearts of us die-hard war-gamers. Not a bad thing, I’m just saying it looks like the 1940 games will be hard to compare with AA50. Unlike AA50 to Revised, where AA50 just whips Revised in every way, and does everything Revised does, but better.
Kinda wish they’d improve on the 1942 scenario again, because AA50 has a lot of room for improvement. (Like applying some of the AAP40 rules for starters - new AA rules, changed SBR rules, no auto-repairing BB’s, China, etc) But I guess if they’re averaging a new game every 8-9 months, we won’t have to wait long!!!
