This modpack is perfect for an SMP with people that like the original feeling of the game, but got bored of just the vanilla experience. So, here are the main things it adds:

-Overhauled worldgen: mods like Regions Unexplored, Nature's spirit, Geophilic, Tectonic, Alex's Caves, Better End and some more elevate the worldgen to a new standard, there's also Aether which adds a whole new legendary dimension;

-New mobs: some of the previously listed mods together with Alex's Mobs add in unique mobs. And don't be scared of the cave centipede. It doesn't bite, well... it does kinda...

-New gear: there are new contenders for best gear, such as: tungsten, terrasteel, spawner, aeternium, and many added with aether. Try them all and find out which one you like the most.

-Base building: build your base just the way you like it with Create and Botania for some automation. And you have storage drawers together with sophisticated storage for well... storage.

-Is there server conflict? Well you have guns from Create: Love and War and airplanes to dispute it.

-Vanilla backport also backports some of the newer updates back to 1.20.1 so you don't feel bad about playing a several year old version.

-Dungeons and exploration: explore through many dungeons added by Aether and Dungeon Now Loading with the help of sleeping bags, backpacks, trinkets and relics. Never get lost with the Journeymap mod and when you're done exploring return home with a waystone.

-Vanilla+ mods: there's also Quark, Supplementaries and Amendments, which all add tons of small things.

This modpack has a Vanilla+ feel with guns. So yeah that's basically the main premise of the modpack.
