Create: Flatworld
This modpack handles the create mod in such a way that it's now possible for you to play on a superflat world without bonus chest or structors generating. So you will be working from scratch to survive.
Thats also the most importend thing. When creating the world you should make your world a superflat world without structors or bonus chest.
Challanges!
Now just playing in a superflat world would be boring, so the mobs that will spawn in the night will progressivly get stronger. Your goal will be to out perform their growth and grow stronger faster than them. If you manage to complete all the quests you will be close to a demi-god in your world and the enderdragen will be nothing but a fly to you.
