	'''Quality''' is a feature of the [[Space Age]] expansion. It introduces four higher quality levels for all items, structures and equipment with improved attributes. The goal of quality is to allow vertical factory upgrading as alternative to ~~expansion~~ in size. Items of higher quality are created by chance when using quality modules in the ~~producing~~ structure. When Space Age itself is enabled, the two highest quality tiers require technology not available on Nauvis. Different buildings and items can have different attributes that can be upgraded. When hovering over something, the attributes that will be upgraded with quality will be marked with a blue diamond ([[File:Quality info.png]]) in the tooltip.

	While players are required to own Space Age to access this feature, quality is a separate mod, and can be activated ~~independent~~ of most Space Age content.

	While speed modules inherently reduce the effectiveness of quality modules, there are cases where using a single speed module can increase the both the output rate of normal and quality items per unit of time (at the cost of more power consumption). This effect is best seen when using a single speed module in a beacon affecting a device with 4 quality modules installed: the increased output per unit time more than offsets the reduced quality % chance. This is a delicate balance though, as adding two speed modules to the beacon is almost always worse (though still better than no beacon at all).

	Another use for quality is decreasing the amount of buildings needed to perform the same production. This is particularly useful in a [[space platform]], where small, compact designs are rewarded with increased speed, as well as needing fewer rockets to build the platform.
