Some of the mods in the pack are:
Biomes O' Plenty - adds many new colorful biomes to explore
ExtrabiomesXL - another mod that adds new biomes to further enhance the exploration element
Dynamic Surroundings - makes visual and audible experience more immersive
MrCrayfish's Furniture Mod - functional and decorative furniture
