This is a self-assembled Create-focused NeoForge 1.21.1 pack (Create 6.0.10) built around heavy automation and tech expansion, pulling in a huge swath of Create addons — big cannons, nuclear, diesel generators, aeronautics, propulsion, enchantment industry, ultimate factory, and dozens more. It's paired with a deep cozy/decoration and food layer: the full Farmer's Delight + Create's Delight ecosystem, Macaw's suites (furniture, doors, windows, bridges, paths), Handcrafted, and Yung's structure overhaul mods for better dungeons, strongholds, temples, and caves. Performance is aggressively front-loaded with Sodium, Lithium, FerriteCore, ModernFix, ImmediatelyFast, Distant Horizons, and several leak-fix/FPS mods — suggesting you're trying to offset the mod count on a machine that feels the weight. The overall intent (Likely) is a long-haul single-player or small-server "build a factory empire in a lived-in, seasonal world" pack rather than a combat or exploration challenge run.
