Custom



Customized was a world type that replaced the normal varied terrain of the Overworld with custom features. Because, as of snapshot 18w06a, it was removed completely due to the rewrite of the world generation, it was then replaced by a new, easy-to-customize but considerably more limited substitute world type called Buffet. Although it is, however, being removed as of that snapshot, Minecraft developer Erik Broes has stated that Customized world types will be returning at some point in the future after Java Edition 1.13, albeit "completely different from before" and with "no more screens of 50 vague sliders".
