Imo units bids and cash are most minimalistic, and therefore should be the preferred option to balance the game.
As for two the official optional rules, Dardanelles closing and SBR interceptors, I haven’t tried those so I don’t know how much it affects the game balance.
Most of us play with NOs, (which is also an optional rule) and this is most fun, so I think that nerfing the NOs is unacceptable within my minimalistic philosophy of game balancing. Reducing NOs are house rules department imo.
What is important to remember, that 2 optional rules was included when the game was released, and two rules were added afterwards, probably b/c of balancing issues. I might be conservative on this, but as long as it comes from Larry Harris, it’s ok, and especially when rules are optional.
Tech and NOs was not added for balancing, but for fun, and Dardanelles + SBR interceptors was added for balancing, so we should consider these optional rules differently.
As for interceptors, I welcome it, b/c it will probably reduce randomness. I don’t think it will influence the balance, but the Dardanelles closing probably will favor allies, I think this item is not a good concept for balancing, or changing the game, even if it comes from L.H. b/c then all other straits should be closed according to the real WW2, but as with all other official rules, I can accept these rules if they makes the game more exciting and entertaining.
I just think at all other discussions on game which influences the game more than the smallest possible change, and then only related to game balance, should be discussed in the context of custom mods and house rules.
As I’m quite interested in the philosophical aspects of things, balance issues vs custom rules/house rules, skill vs luck etc.
Often I get the impression that many of you really don’t like AA50 that much, but maybe you see AA50 as a platform to build on, with the purpose to make your own games…?
