Flexible Games Builders Pack

This pack offers many tech-based mods to learn, master, and expand your automation empire. And do so with limited mining grind-work. Build giant reactors to power your ever-growing base, and eventually never need to mine again with RFDimensions and void miners. Focus on building, automating, and designing.

No Create mods at all in MC 1.21.1 version. No Thermal either.
Mekanism, Immersive Engineering/Petroleum, Oritech, Industrial Foregoing, PneumaticCraft, Powah
AE2, Storage Drawers, Sophisticated Backpacks
Draconic Evolution and Infinity Cells for the end-game.
Custom ore-gen across the board, with Void Miners for extra cheese.
A few custom recipes for further grind reduction.

This modpack is featured on the Youtube channel Flexible Games, come by some time. https://www.youtube.com/c/FlexibleGames
