Explore is a Giant Expansion on Vanilla , making Exploration way more Interesting and fun and slowing down progression so you progress naturally and in more Creative Ways than getting full diamond in your first 20 Minutes. Explore combines a lot of different Mods , makes them rely on each other and removes almost all overlap between them , providing for a clean and unique Experience.
Theres also a Book you get at the Start called the Explore Atlas, wich helps you get into the modpack :)
Have fun exploring -Arackulele :0
