For my own bit, my resolution process was as follows:
I. Identify Objectives (what is each side trying to do)
II. Identify Intelligence: What does each side know; and when do they know it? Careful evaulation of the sensor rules is helpful here, and this interacts with I and III.
III. Make Plans: Based on what they know about who is here, what they probably want, the relative admirals intel at various points, etc - make out each sides plans. Thesemay change.
IV. Run those plans through the rules. I didnt roll every shot - instead doing a rough lanchester equation at various battle stages. (Missiles and espc fighter strikes got handled as salvos; of course). Figure out who dies faster at each part if the engagement, and how each admiral is going to try to change those things to acheive his objective. Im looking at resilience and firepower, absolute and relative, as a function of range and ammo and the like. Do fighters go in first? Or second? Pros and cons to both. For example, do I need to blow past the enemies LNGauss to wreck the yards with NACs? Or if I have the LNGauss, can I lay off and bombard and force them to come to me? If the enemy has every advantage, do I retreat? Can I use along range strike to lower their firepower enough to win a close engagement? Admiral skill and luck and the like play in here. Dice are rolled to create noise, but dice arent likely to change W and L unless things are quite close.
V. After figuring out the numbers behind the narrative, I write up the narrative commensurate with the math.
I probably spend 8-12 hours on each major battle, from ‘what are each forces orders and objectives and motivation level and order of battle and maintenance status’ through ‘this is the final body count’. Honestly, in retrospect it was a labor of love, that I could not do again (unique life circumstances gave me a LOT of spare time and mental energy - and even so I burned out fast).
That said, Im actually pretty proud of what came out, while it lasted. That much fidelity may just not be a thing thats doable, though - and if it burns out GMs, it doesnt work, however pretty one battle report might be.
For a new game - I will try to watch, but I dont think I have the energy to play again.
