Probably redundant and absolutely unoptimized, this absolute behemoth takes about five gigabytes of memory to run smoothly. This is the result of a friend and I listing off mods we wanted in a pack if we were to make one. Lots of late-game stuff.

The tech mods here are the ones that use the RF power system. This is the usual crew of Mekanism, the Thermal series, EnderIO, and more.

Extreme Reactors and NuclearCraft, because two atomic mods is funny.

Twilight Forest, Aether, Recurrent Complex, RFTools, and the OTG with Biome Bundle to make adventuring a bunch more fun.

Hardcore Darkness, Grue, Weather2, and Chance Cubes to make that adventuring a lot more exciting.

Treasure2, Loot Bags, and Reliquary to make it worth the trouble, with Iron Chests and Backpacks to put it all in.

Decocraft, Crayfish's Furniture, and Bibliocraft to make your return home much more inviting.

Googly Eyes, Hats, and Inventory Pets for the charm.

Also contains mods that make life much more convenient, such as Veinminer, Torchmaster, SimpleHarvest, Snad, Prefab, More Overlays, KleeSlabs, and Agricraft.

Also KAGIC, but I don't know what it is or what it does.

If you're reading this Christian, they approved it and I'm working on a server.

[UPDATE] Server made and it works. Need to clean it up and ship it to Curse.
