I have like 60 some odd, I stopped counting at 61.
If I had to pigeon hole the technologies right now, based only on what I’ve been able to do and what I’ve seen done here is the break down I think would work best:
Advanced Technologies: Cost 6 IPC per researcher and include
Long Range Aircraft (This one is just crazy powerful in this game due to it coming the instant you discover it. Suddenly naval assets you thought were safe are artificial reefs for the fishies.)
Improved Factories
Mechanized Infantry
Heavy Bombers (Just as powerful as you think they are.)
Moderate Technologies: Cost 5 IPC per researcher and include
Jet Fighters
Improved Shipyards
Radar (I would add this to Battleships)
Paratroopers
Minor Technologies: Cost 4 IPC per researcher and include
Advanced Artillery (You would think this is higher, but it’s just so hard to get Artillery to the enemy in this game!)
War Bonds (I would amend this so that a roll of 6 allows you another roll added to the first)
Rockets
Super Submarines
I would also give all Battleships, regardless of technologies, the right to have AA Guns on them and make all Aircraft Carriers two hit units.
Earlier in the game this will really help Japan, but later it will really help England and America, so it balances out.
