RPGYOGE

This modpack focuses on roleplaying and exploration while retaining the feel of vanilla. There are more Weapons and armor, added structures like villages and dungeons in Recurrent Complex. Caves and biomes are also improved in mods like Subterranean Waters and Biomes o'plenty. There are two added dimensions, the Aether and The Twilight Forest.
