All quality tiers (Normal through Epic) now perform identically to Legendary. You still see quality colors and labels if you want the look, but everything functions at top-tier performance. The mod removes the need for quality modules, machines, and combinator filters while keeping full compatibility with vanilla saves, the Space Age expansion, and other mods that reference the quality system.

This mod works by directly modifying the quality prototypes in data-updates, copying the Legendary multipliers to all other tiers. That means every machine, weapon, turret, module, and structure automatically benefits from legendary stats—no item-by-item patching required.

No Quality Grind is perfect for players who want to enjoy top-tier performance without the grind or complexity. Your megabase runs faster, cleaner, and with fewer headaches, while staying true to Factorio’s balance and progression.
