Sometimes less is more.

Never had so much fun playing Minecraft before.
Of course, some people may turn their noses up at unusual content, such as: no End dimension; reworked enchanting; coordinates tied to items... but it actually makes the game slower and really different from most modded experiences, forcing you to play in a different way.
The pack achieves a HUGE integration between each mod. Everything just connects. New textures, recipes, loads of content made specially for the pack...
It's a really well-thought vanilla overhaul. It feels more free and like a true sandbox game.
Of course, sometimes there may be some bugs due to the integration of the mods, and even though this happens all the time with many packs, this one is so well made that when something is out of place it sticks out. However, the amazing people developing this pack try their best on polishing the experience.
