well warstuff rules are simple and I gues they fit nicely in gpt memory the ruleset is here and is magnitudes simpler than warhammer https://onepagerules.com/portfolio/one-off-games/ - I just copy pasted the whole ruleset into a message prepended by "Consider a wargaming system built with these rules:"

this is a sample prompt afterward:

> create a set of units using these rules, themed around warhammer 40k

this is what chatgpt came up with, it's impressive as I just set a theme, and it dig up appropriate original special rules that fit within the ruleset:

Sure, here are three examples of units themed around Warhammer 40k that you can use in your wargaming system:

    Space Marines: Quality 4, Special Rules: Shooter, Tough, Cost: 50pts

    The Space Marines are a heavily armored and well-trained fighting force, with a Quality value of 4 reflecting their combat abilities and morale. They have the Shooter special rule, allowing them to fire ranged weapons, and the Tough special rule, making them more resistant to damage. Their point cost is 50, calculated by multiplying Quality 4 by 10 and adding the point cost of the special rules.

    Chaos Space Marines: Quality 3, Special Rules: Shooter, Daemonic, Cost: 40pts

    The Chaos Space Marines are a corrupted version of the Space Marines, with a lower Quality value of 3 but the same Shooter and Daemonic special rules. Daemonic units are immune to morale tests and can only be killed by a roll of 6 on the melee attack. Their point cost is 40, calculated by multiplying Quality 3 by 10 and adding the point cost of the special rules.

    Necron Warriors: Quality 2, Special Rules: Shooter, Reanimation, Cost: 30pts

    The Necron Warriors are an undead race of robots, with a Quality value of 2 reflecting their lower morale and combat abilities. They have the Shooter special rule, allowing them to fire ranged weapons, and the Reanimation special rule, allowing them to automatically recover from being stunned instead of taking the Recover action. Their point cost is 30, calculated by multiplying Quality 2 by 10 and adding the point cost of the special rules.
