Balance wise, I like this mod better than marathon because it makes final products harder, only. But What do you do for final products that are used in other final products, like yellow belt in red belt?
I didn't alter belts, or anything that is used to make something else. Also for upgrade recipes that use an earlier version in the recipe, it's still just 1 (not 10). e.g. Mark two assembly machine still req. only 1 mark 1 in the recipe.
