I was never a big fan of the unit bid. I posted years ago about bidding for NAs in revised. Also I wanted an option to play minor victory, which I think also helps the Axis. I used to like to play Classic with Restricted russia and Weapons Development Bonus. If this doesn’t eliminate a bid it should at least reduce it. I used to advocate for that option in the Axis & Allies Member’s Cluib (AAMC), but there wasn’t much interest.
I like the idea of playing with interceptors, and I like the option to play with the Dardanelles closed. But these don’t replace bidding. nicely. I’m not much interested in ‘house’ optional rules, but for optional rules to replace bidding, you need lots of them, they each need to clearly favour one side, and none of them should be crushingly powerful on their own.
The Revised NAs were the best system for non unit/IPC bidding. You could bid up to twelve to play the Axis - which I think is more than high enough a bid. Best of all, we’d be playing practically OOB! If the rules for NAs had been to use any, all, or none (instead of strictly even combinations), bidding as such would be playing one hundred per cent OOB! This is how NAs should have been handled. :(
Alas, with the awesomeness of AA50, the upcoming curiosity of AA42, and my recent acquisition of the 1981 Nova Games edition (which I’m dying to try), I don’t see much revised in my near future. I don’t think alternate bidding works nearly as smoothly in AA50 either. :(
One system I like is to play back to back games switching sides. A player is declared the winner as soon as they’ve won a game with each side. This is nice for tourneys. Sadly A&A is too long for this - especially considering you could play indefinitely with the same side winning.
Best of luck in your endeavors!
