We know that the Global '40 techs will be the same (in name, if not in function) as the AA50 set:
Advanced Artillery
Rockets
Paratroopers
Increased Factory Production
War Bonds
Improved Mechanized Infantry
Super Submarines
Jet Fighters
Improved Shipyards
Radar
Long Range Aircraft
Heavy Bombers
So: why not start playing Pacific '40 with the weapons development rules in place, just to get used to how these are going to affect the game?
Obviously, it’ll mostly be the US and Japan trying for these unit upgrades (the Chinese won’t even have the option to do so, the UK and ANZAC forces will mostly be turtling up), but usually the two big forces in the Pacific end up having roughly the same economy at the mid-point of the game, so it shouldn’t be too unbalancing to include the weapons development rules (they’re optional anyway)… thoughts on this?
