Well that would just be a small detail as resources are not that unavailable, I wanted to simulate the fact that coal-fired ships would have been of some benefit to Japan.I could reduce the available resources in production slightly (on the home island). Quite a simple thing to do. Would you be happy with that?
So far we have W1 class and Shirataka ML class and one allied ship
No it isn't just a small detail. You haven't thought through this logically at all. Do you really think that JWE/Symon, a qualified naval architect wasn't aware of coal propulsion and somehow didn't incorporate it into the existing abstractions. Just like whether a ship was single/twin/triple screwed isn't somehow incorporated into the abstraction.
Your proposal in post #6 of reducing fuel to 1 clearly demonstrates you haven't thought this through. All that fuel status would achieve is to permanently limit your ship to moving at a maximum of 1 hex per day and suffering the out of fuel penalties. Wouldn't be long before it sank on its maiden voyage. Is that what you really want to achieve.
The game already accounts for Japanese Home Island coal production by the quantum of Resource centres located there. Or did you think the Home Islands were pre 7 December 1941 awash with iron ore, bauxite, rubber, etc. Game resources are used to generate supplies. It is all an abstraction as clearly evidenced by the fact that aircraft consume supplies, not fuel in order to fly.
For the purposes of movement, no ship consumes supply. Hence you cannot directly adjust for consumption of coal burning ships. Their characteristics have to be abstracted. Why don't you look at what JWE/Symon did with those ships and see how you can improve on what he did.
Edit: Actually, you get other problems if you reduce the fuel to 1 but keep the endurance at the previous level of say 3000. One is that you risk a crash to desktop. If that is avoided, you have created a nuclear powered ship with minimal refuel requirements.
