Our latest addition: Biomes O' Plenty!

Biomes O’ Pleny Mod is a mod that is designed to give players a better Minecraft world to explore, and more of a reason to explore it in the first place. There are a lot of realistic biomes, some fantasy biomes, and other cool things added to the mod.

There are also a few new mobs, such as the Jungle Spider, which spawns in tropical/jungle biomes at night, and the Mutants, which are essentially clones of Zombies that only spawn in the Wasteland, and have different drops.
It also adds custom achievements, all of which are just picking up blocks from certain biomes, like red rock, glowflower, etc. They’re just meant to give people more of a reason to explore.
Village generation has been changed to allow villages to spawn in most flat, livable, and realistic biomes (No fantasy biomes). Villages don’t spawn in any other vanilla biomes aside from the Desert and Plains, however.
Emerald ore can be found in multiple biomes outside of the Extreme Hills biome. I won’t say which ones, as it’ll ruin the fun of finding them on your own.
