i think a Rarity system for Items and Skills would be incredibly useful for developers making larger-scope games with an emphasis on progression. a simple way to alter the hex color of the Item or Skill's name text, as well as the ability to create a custom list of named Rarities with the option to make the Rarity names visible in-game would be all thats really needed.
heres an example of the Rarities i have in mind for my 8~ hour RPG im creating in the engine. this would be incredibly useful for distinguishing the early game weak items and weapons from the late-game overpowered ones as you progress
i really think this is essential for those like me making big adventurous RPG's in this engine. please make this happen
