Create Everythink is a modpack with a focus on Create, but also Mekanism, Immersive Engineering, Botania and Thermal. With slightly changed crafting recipes and heavily revised ore generation (Large Ore Deposits). Mods are also available for a lot of decorating. You can also choose the magical direction and work with Forbidden & Arcanus or Ars Nouveau. There are a couple of quests too.
