You make valid points.
It’s not so much that the purchases are wild. A lot of time and thinking has gone into the purchases.
How can these seemingly odd purchases provide long term benefits/strategies, without being detrimental to the game?
The strategies are based around a notion that most players open with stock standard set plays.
The A/C for Russia turn 1 works.
Now a German player must devise a way to counter it, and it is not as simple as it seems.
Another option gamed successfully are two Russian bombers as a turn one purchase.
It was done initially as a joke: then came the necessity of having to make it work.
Russia didn’t fall.
It’s the scripted scenarios that I try to avoid. Some times however, they do need to be done.
I do not know what bidding is.
Your point about the dice is correct.
I’ve played AA Mark 1 through to this A & A 2nd edition for fifteen years. Love it.
