Ecospherical Expansion is a mod aimed towards recreating biomes with more diversity and aesthetically pleasing scenes. Additionally, this mod adds custom integration with the Large Biomes and Amplified world presets; While also adding 8 new world presets to choose from.
NEWER VERSIONS (1.21+): This mod will not be updated anymore, it has been replaced by my newer mod https://modrinth.com/mod/hydrological

NOTE: Versions below 1.20.x do not have world presets. In those versions, this mod simply redoes the vanilla biomes.
