We should add Galacticraft because it will add more content to the server. Plus there's spaceships. https://micdoodle8.com/mods/galacticraft
Our current Minecraft server is vanilla - there are no mods required on the client's side to play on the server. Not to mention "Galacticraft" has a latest supported Minecraft version of 1.7.2/1.7.10. The latest is 1.11.2 - Galacticraft is far, far behind.
Here is a list of compatible/semi-compatible plugins that can be used on the server. https://www.spigotmc.org/wiki/spigot-1-11-plugin-compatibility-list/
I have a lot of experience with Galacticraft, but adding it alone will make the server a Tekkit server. It's supposed to be vanilla. However, don't lose hope, if you keep being a good boy we might actualy get one.
