SteamForge SMP is a modded survival multiplayer server that is all about creativity and community and big builds.
It is launching today so it feels like a fresh start that is good for new members.
The server runs mods like Valkyrien Skies and a bunch of Create content like Steam and Rails Diesel Generators Factory Must Grow and Big Cannons with extra addons. There are more mods too.
It is not pay to win and you need your own copy of Minecraft to play.

ATLAS V3 is a modded server that is all about going bigger than normal Minecraft. It has this space vibe where you work your way up and aim for the stars.
I saw that it includes Valkyrien Skies so people can make vehicles. It also has Create 6.08 and Mekanism with other tech mods so you can build machines and automate stuff.
There is CC Tweaked for computers and TACZ with a bunch of additions for gun combat. It also mentions war related mods plus custom planets and space mods so you can explore and fight in a more sci fi way.
It sounds like there are lots of extra features too and you are supposed to hop in and try it.GG.MINEWIND.NET New Server IP
