If I got it right, it is already in the game engine. Give the torpedoes a replacement rate and there will be a global pool of them. It's even used in stock (for the Ohka).ORIGINAL: el cid again
If my understanding is correct, they will implement tracking of some devices - so you then may get limited torpedoes.
But I don't think it is a good idea to use this feature as it is now. First, you can not do anything to save torpedoes (e.g. order Betties to do naval strikes with bombs or restrict strikes to valuable targets only). Second, these pools would be hidden - the player can not see, if he has 10'000 or 10 torpedoes left. I think using the feature as it is now would lead to eratic and frustrating behaviour.
Sounds interesting. Do you combine witp with a lot of pen&paper work, or which game is it?In my games (which require vastly more human effort on the logistic side) we track every last torpedo by model and location in theater.
