Aether SMP (fog bad modpack)

This is a Tech Modpack, it contains mods such as Thermal Foundation, 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.

Oh wait you're a Builder? No worries! It also has many custom blocks for you to play with.

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.

Some other mods that it has is Project E, Applied energistics 2, Mystical Agriculture, Open Blocks, Random Things, etc. 

I'll leave a disclaimer about recommended RAM here, feel free to read: 

If you have 8GB ram, put 4,5GB
If you have 16GB ram, put a bit more, or the same ammount as 8GB RAM people

 Have fun building, exploring, making factories, etc.
