Quality modules have a much higher quality increase percentage, but also increase energy consumption and decreases speed much more. Helps to reduce the randomness of quality without making it feel cheaty.

Quality module 1: +20% Quality | -20% Speed | +100% Consumption
Quality module 2: +30% Quality | -30% Speed | +200% Consumption
Quality module 3: +50% Quality | -50% Speed | +400% Consumption
