Its highly recommended to use the datapacks provided as they increase compatibility and add more features.

I'll upload the datapack as a seperate project soon.

This modpack contains various optimization mods, shader support, a few QOL changes, and tidbits of vanilla plus tweaks.

Tons of new foods, biomes, player skills and classes with their own abilities, weapons, armors, artifacts, metals, blocks, materials, more animals, mobs, bosses, dungeons, structures, new dimensions and planets, harder difficulty as you travel and as you progress in the game.

Main Additions

- Husbandry

Experience rotating seasons, with crops compatibility, new crops that you can process into ingredients and new dishes using the Farmer's Delight, Let's Do series, and Bountiful Fares mods. Brew beers and create wines and other dishes in the Let's Do series.

Find tons of new peaceful and potentially dangerous animals on your adventures.

- Engineering

Using Create and various Create mod addons, create farms and factories to optimise and automate metal and material processing. Using Knight's Quest, Tinker's Construct and Mythic Metals compatibility, create new metals, alloys, armors, weapons to help you fight numerous mobs and bosses, and use powerful tools to transform your terrain and pursue your building projects. Armor trims can imbue your armor with special traits and abilities depending on the material. Tom's Simple Storage is also a cheap and intuitive way of organising and searching for your many items easily and quickly.

- Exploration

Use new backpacks, boats, planes, and artifacts to help you traverse the new biomes and climates. There are tons of biomes, combining the fantastical and charming natural elements of the Oh The Biomes We've Gone and Nature's Spirit mods, plus a plethora of new structures and progressive dungeons. The Lithosphere mod creates immersive mountain ranges, valleys, plains, and oceans. This mod also uses a continent style generation. Generally certain biome temperatures will generate near each other and fill majority of a continent, other continents contain different climates and biomes but continents are spaced far apart.

New dimensions and planets. Explore the otherside, a sculk dimesion, and Minecells dimension as an intermediate level of combat and exploration. Then Explore outer space and parts of the solar system to find new mobs, artifacts, bosses and structures. The moon and mars will contain difficult mobs and powerful artifacts, however, be ready for Venus and Mercury as they will be filled with terrifyingly dangerous creatures, horrific pirates, and powerful bosses.

- Gameplay

Refreshed Combat. The better combat mod along with other weapon mods adds a fresh spin to combat

Lively Homesteads! Tons of new blocks. Including, new stones, bricks, polished variants. New stylish blocks, new decorative blocks and tons of new furniture and lamps and such.

Economic!? A create currency mod adds money that can be used with your friends to create stores, markets and trade materials and valuables.

Player Raids! If you would like to, you can create turrets, cannons and use planes to raid other players.

General Progression:

The game will get progressively harder as you play. As you enter the nether and end, the game will enter new gamestages; increasing difficulty by new mobs spawning along with more health and damage. Undead raids can also occur.

As you get new gear and travel, the Otherside and Minecells dimension will prove to be an intermediate challenge. As you level up your character, automate more factories and gather more materials and get more powerful, you can either traverse the nether for new bosses, or travel to space and be limited by the protection of a space suit, but find powerful artifacts, challenging mobs, and as you get to the endgame of Venus and Mercury, be pushed to your limits by fearful sights, creatures and dungeons.

Future Plans...

More Nether mobs and bosses. (Perhaps a special warden for each vanilla dimension with special abilities)
More End mobs and bosses (As of right now there is some more stuff in the end, such as structures and a couple new mobs. However, it is still a bit plain for my liking so ill will continue with my datapack to add more bosses and mobs)
Continue enhancing space (Eventually I'll be adding more dungeons and variants of mobs to Mars, and strong mobs and bosses to Venus and Mercury. This will probably be in a month or two) I will continue to update this modpack and keep it up to date. I'll end up adding more features and compatibility through datapacks as well.
