Ownit's Experience

A collection of mods for a Vanilla+ Experience with mods including Immersive Engineering, more biomes, and some magic extras, and most importantly, more decoration blocks for those that like to build nice looking houses. Its built for the purpose of providing a lightweight but content-rich experience for a dedicated server to play with your friends. The basics of this mod-pack is to provide a experience as close to Vanilla as possible but with added extras, lightweight enough for most servers to handle. 

The aim is to not change anything about the original Minecraft but merely to add new stuff to do while you play.

This means that this mod-pack doesn't really change the starting experience at all, you spawn in the world as normal, what you will notice however is that the world is more alive than the original Minecraft provides with villages now has villagers that has different professions, you will also notice new biomes with several new trees. One nice thing also provided is a tree-cutting mod to get you started quickly, chop down the lowest log in a tree and the whole tree falls down. JEI is also included of course, to lookup every recipe for the new mods. 

Immersive Engineering's mod makes mining a bit more fun but not overpowered with a whole new set of tools to aid you in the quest of caving.
