If your goal is to make a category where the speedruns would go up to the 500 turns, maybe we have to do a category that would only allow you to do a score victory with Game Speed on standard and the Limit Turns by game speed.
I've just look at the discord, I'm sorry I didn't see you already talk about it and I feel like Acrumus is kinda right when he says it looks like ancient%. Victory: Science/Culture/Domination/Religion/Diplomatic/Score Victory Conditions: All victory conditions must be activated Game Modes: All game modes must be disabled
This rule should prevent runs less than seconds/minutes.
