This is the modpack used by Boodlyneck on his Modded One Block series on YouTube.
The big advantage of the One Block play style is that it makes adding new mods with new world generation fairly easy.
I would like to thank HorribleNerd for creating CobbleGenRandomizer which makes this modpack possible.
When you first create the world it takes a few seconds to get your one block, so no need to worry.
It will keep growing every week as we add new mods until the series is over.
