The goal of this mod is to make quality feel like less of a gamble, allowing you to naturally produce good quality factories at the cost of power and speed. Tweaks values to what I feel offer better gameplay than the original mod.

Quality module 1: +20% Quality | -5% Speed | +100% Consumption
Quality module 2: +30% Quality | -10% Speed | +150% Consumption
