I think the real challenge with A&A Europe is during 1 vs 1 with experienced players. Because the allied aspects of debate and compromise simply don’t happen. Whenever I play my friend Cat - she always without even a thought sends 4 fighters and 2 bombers to Russia ASAP from the US and UK.
When we play with more people (like her boyfriend and his housemate) you always get the UK/US ‘whining’ or wanting to do their own thing. Which makes it easier for Germany.
I must admit I played Europe (normally play revised/AA50) for the first time in a long while recently. So I had forgotten about the ‘unstoppable’ version of the infantry/tank push mechanic - and spent time consolidating forces for a crushing victory in Belorussia - which - ahem - never actually happened! (Especially once she’d added all those allied fighters to the pile!)
