This isn’t about features or content size, but polish. From a player and developer perspective, here’s what consistently separates good mods from great ones. Performance awarenessHigh-quality mods avoid ticking when unnecessary, cache results, and respect server performance. Consistent behaviorItems behave predictably, configs work as expected, and nothing breaks silently. Clean UI/UXMenus don’t lag, text is readable, tooltips explain behavior without external documentation. Compatibility mindsetGood mods avoid hard conflicts, use proper tags, and integrate with existing systems instead of overriding them. DocumentationEven minimal README files or in-game descriptions dramatically improve user experience. None of these are flashy, but together they’re what make a mod feel professional. Interested to hear what others prioritize.
