About this Modpack

ModPack Banner

A great ModPack to play with friends without a worry in the world

🔥 Performance

It's main focus is performance, it runs great, period. Thanks to mods like Sodium and a lot more that I can't even count your game will run WAY better than Vanilla for sure.

👯‍♀️ Multiplayer

This ModPack includes the e4mc mod, that gives you a server link whenever you open your singleplayer world to LAN so you can invite your friends to play on it. Besides, it includes a lot of optimizations for big & small servers (plus some quirks for offline users, but nobody told you that).

🌸 Quality of Life

It comes with Multiple mods that enhance the Vanilla experience to just be more comfy. Like the formentioned "e4mc" mod, which allows you to play singleplayer with your friends, "Zoomify" for insane zoom activity, "Jade" for info of whatever you're looking at, and others that feel equally great 👌

😫 Seriously... ✨useful✨

This modpack is supposed to be the last modpack you should EVER use for Vanilla gaming, and it's thought with customizability in mind, thanks to mods like "Resourcify" and "Iris", you can install shaders, resource packs and data packs all within game!
And if that's not enough, then "Skin Shuffler" is for you! An in-game skin swithcer that allows you to have your own library of skins ready to change whenever you wanna, all without quitting the game, now that's ✨useful✨

🐧 Linux, Windows & MacOS Support

I Daily drove Linux for a while, so for this modpack to work on it is really important to me, but now I switched to MacOS and Windows on the Daily. It isn't really thought for now to make it work better on MacOS, but it still works, and now that I daily Windows for gaming, I can confirm that it works pretty great!


🤓 Reason for it's existence

I felt like Minecraft should come like this as default, resources are still very tedious to install, and something as simple as multiplayer is still insanely difficult for no real reason. So I decided to change that, cause I just wanted to play with friends, family and others and it just isn't possible as is, so that's why this exists :D


🙌 Donations

If you really liked the project and would like to help me on my other endeavours (art & college) I would really appreciate your support :)
