Kingdom Hearts 3 Optional Content (WIP)

Kingdom Hearts 3 is a game with a lot of big maps. Needless to say there's a lot that's not required in them. This list will cover all of that.

Cooking is obtained in Twilight Town after getting ingredients for Remmy. To cook, you gather ingredients and find the recipe in the list. There are five types: Starters, sSoups, fish, meat, dessert. When eating a meal you can eat one of each of these types, which is advisable as this grants the greatest buff. When cooking you play a minigame, which is varied depending on the course (chop veggies, crack eggs, etc.). These are easy, and it's also easy to get excellent, which grants a + version of the food. After cooking enough you'll get a star. Every other star gives a gift, the final one being a new keyblade. This is something that must be looked into.

Classic Kingdom is obtained in Twilight  Town at the same time as cooking. It's a series of Game and Watch-style games themed after classic Disney and Mickey moments. Upon completion of these a keyblade can be obtained. These minigames can be accessed in the Gummiphone in the menu, and can also be found in the Union Cross mobile app.

Crafting has been around since Kingdom Hearts 1, and is present now too. In KH3 it's quite similar to how it was in KH2, you can drop your materials off at a moogle and, if you meet certain requirements, you gain a reward, like an AP up or the option to buy materials from the Moogle store. Looking into the crafting menus themselves, you have the option of making several items, from weapons for Useless and Half Useless to armors to stat boosts. The ultimate purpose of all this crafting is the Ultima Keyblade, which has the best stats in game. Unique to KH3, however, are the photo missions, which utilize the Gummiphone and require the player to take pictures of things like heartless and in-world objects, as well as keyblade upgrades, which keep the keyblades with your favorite transformations viable into end-game.

The Gummiphone has a feature worth noting: the lucky emblems. These are introduced in Twilight Town but appear as early as Olympus Coliseum. There are ninety of them in-game, and taking pictures of them can provide items to compensate for the search.
