Rogmunity

A collection of mods chosen by Roganz with help from the Rogmunity.
Beyond the vanilla experience, the main changes are as follows:
Botania\Ars Nouveau add magic systems, one flower based and book based
A fair few mods that add dungeon changes and biome changes, as well as loot chests so multiple people can loot the same chest, getting unique loot each
Create adds engineering, automation and things. MANY mods interact with it, including dungeons with create stuff, magic that links with it and such. Also, Immersive Engineering does similar things, including some very cool wiring and electrical based things.
Gravestones. Death drops stuff in a grave you can get back
Just Enough Items and a load of mods mean you can look up loads of things, including what villagers trade, mobs drop, etc.
Backpacks and storage that links together well with addons, allowing a centralised storage for the early game.
Planes. Jetpacks. Waystones. Twilight Forest.
