Shattered Simulation is a very generic kitchensink and I'll spare you the motivational speech.
The Main mods are Create, Mekanism, Modern Industrialization, Iron's Spells'n Spellbooks, Ars Nouveau, bunch of addons for all of those and a lot of QoL
the neat gimmick is Shattered Realms which actually FORCES you to get airships or any floatation device to move between islands that sometimes span atleast 3 blocks in distance (sometiems 400 in vertical space)
Have fun, don't blow your home up with the Stellar Remote and obviously
enjoy Shattered Radial Menu, my custom mod for it (free to use in any pack)
