I am still not sure, why people are overly concerned about SBR;
We have now played three AA50, granted house games, utilizing the partial AA50 rule set, we have put together here online,
some points to consider;
Item:Players have always used USA/UK bombers to bomb Germany,
now add Italy(same territory really as Souther Europe) to your list,
in our 3 games, it was not more of a factor, then usual, some hurt, but not overwhelming. (Italy? giving Germany less attention, priceless.)
(and, yes, our USA, UK players bomb every round possible, they love their bombers,
even, more bombers then usual were in play-cheaper.)
Item:Noted, This AA50 game seems more mobile, w cheaper Naval units, new game mechanics, lots of action, get ready to lose those bombers.
Brief point, screening (at 8 IPC) destroyers, backed by cruisers are defending at 2/3, are soaking up a lot of attacking air power, costing 10-12 IPC. A subtle, but steady economic loss. The same results happened in the second game.
By the third game, everyone, began buying more subs to counter the larger naval deployments.
Air power may be losing dominance, fighters will likely have to get cheaper
(at least 8 IPC,) to stay in the game( Next game Rev-LOL.)
Hell, even the Germans/Italians now seem to have credible naval operations.
Item:Disclaimer, of course our results, might not be yours, and yes we play with some AARHE rules, which could modify our results further.
