This is a Tech Modpack, it contains mods such as Mekanism, Thermal Foundation, Industrial Craft 2, Industrial Foregoing, etc.
But it also has Exploration mods, like Tinkers' Construct, Construct Armory and The Twilight Forest.
If you are not satisfied with those, it still has Magic mods like Botania and Astral Sorcery.
Oh wait you're a Builder? No worries! It also has Chisel.
Basically you can do whatever you want on it, I'm sure everyone will have a good time playing it.
The Modpack also has an optional custom generation, so people with weaker PCs can still play it in a normal world, it's called Biome Bundle, it custom generates biomes using only vanilla blocks, it doesn't add anything; speaking of custom generation, it has 1.16 Nether generation, as well as new stuff from 1.16 (campfires, lanterns, netherite, etc.), all thanks to Future Versions.
Some other mods that it has is Project E, Applied energistics 2, Mystical Agriculture, Open Blocks, Random Things, Immersive Engineering, etc.
I'll leave a disclaimer about recommended RAM here, feel free to read:
If you have 8GB ram, put 5GB - 5,5GB
If you have 16GB ram, 8GB ram
I would recommend at least 6GB but if you use optifine and stuff you can run with that
Have fun building, exploring, making factories, etc.
