This mod pack has a focus on exploring, combat, and setting up a minecolony! There are many mods that add some quality of life changes like Farmer's Delight with many addons to support some of the other mods in the pack, as well as spice of life, which gives you extra hearts for eating a variety of foods. There are some mods that add a bunch more mobs like Alex's Mobs and Super Mobestiary. There are a few that change the vanilla biome generation as well as adding structures and some more! These include Biome Makeover, Additional Structures, and Dynamic Trees. There are a few new dimensions thanks to the mods Darker Depts and The Forgotten Dimensions.
Some other changes to note are that Waystones are included and have been configured so that it does not cost XP and that you will experience more sound thanks to combat music, ambient sounds, and many many more music discs!
This is also great for multiplayer as Minecolonies has integration for other colonies, cosmetic armor slots, and my favorite mod Lootr which replaces loot chests with separate inventories for every player!
