Having an Animal Crossing New Horizons (ACNH) all DIY recipes checklist is important for players of the game, as it helps them keep track of which items they have collected or crafted and what other items they need to obtain. This allows players to make the most out of their in-game experience, being able to quickly identify which materials are necessary for crafting specific items. With this checklist, players can also mark off their progress as they acquire new recipes and materials.
