I would basically copy the beginning of the game, slimmed down to save on memory for the AI, and then I would try to make a somewhat faithful remake of the game based on what it shows, if you could provide like, a general timeline of the game it would be much appreciated!
I will also definitely link the game in the description when I publish the scenario so as to attract more attention to the game and maybe even the Patreon, I sadly am broke AF and cant support myself.
