Various mods including waystones and travelers backpacks to give you an updated Minecraft experience, where you can choose to stay mostly vanilla or build new things with Create or Applied Energetics. With multiple storage mods and lootr so you can play with friends, there's different routes for you to follow. A couple different structural mods are also put in so you can experience a new feel to some of the older non-updated structures. graves makes it so your items don't shoot everywhere at your death, and be picked up by the mobs that may kill you. Have fun!
