Cipop is but a combination of two modpacks present on Twitch/CurseForge, Hexxit Updated by HaoShern and Tekkit Classic Reloaded by Glennyo. Some other mods have been added, such as the JurassiCraft mod.

Hexxit was a popular modpack back in the Minecraft 1.5.2 days and it focused mainly on exploration and adventuring through the world and diferent dimensions, bringing somewhat of a RPG take to Minecraft.

Tekkit Classic however was another popular modpack made for Minecraft 1.2.5 and it focused on base building, industrial machinery and automation.

Since Cipop is a combination of those two, you can have both experiences in one pack. Also, with the addition of JurassiCraft, you'll be able to bring prehistoric creatures back to life.
