This modpack was mainly made for some friends, but you can go ahead and use it however you want. It is a "kitchen sink" modpack meaning that it does not have a specific theme and is just a list of cool mods. It is mainly made up of Create and some of its addon mods, and it has some other equipment mods such as Tinker's construct and Irons' spells and spellbooks and QoL (quality of life) mods such as Tom's simple storage, Sophisticated chests, Quark, etc.
This modpack was mainly refined for multiplayer / server use. That is why there is the voice chat and radio addon mod within the modpack. It was also made with low performance computers in mind too, which is why there are so many performance mods.
As I said, this modpack is not a "serious" modpack, and is only made for mates, but that shouldn't stop you from using it. Try it out, have a blast. You could even use this modpack as a base, and add your own twist to it, personalising it.
Have fun!
