That'd make me happy, I want to work on the campaign without having to sweat getting the AI to act decently
The mods that are REALLY needed are new ships, and ideally a new torpedo type (a sub-launched mine). One other mod, if someone figures out how to make a Panama Canal, then the same technique in reverse can be used to make REEFS.
For ships (japanese, allied don't matter at all, IMO) we need:
~300 ton sea truck ("Sugar Dog")
Kaiboukan
Armed Trawler (with DCs unlike the one in game now for allied)
Tiny coastal subchasers (modded PT boat?) ~100 tons, wooden (1xAA gun, DCs)
Small (<1000 tons) tanker ("Sugar Baker Sugar")
Small (<1000 tons) merchant ("Fox Tare Dog")
None of the above are the "sexy" ships people always want like Shinano, instead, all of the above are the most likely targets to actually be seen by players. No question, the best "bang for the buck."
