About this Modpack

header using new minecraft keyart
Welcome to MC: Steam Deck Edition, a modpack designed as an alternate take on if Mojang partnered with Valve to make a portable edition of Minecraft that Valve controlled, like 4J Studios and their Minecraft editions.

I have been itterating on this modpack for months, but have put so much effort into the little details that I thought I'd package my assets with the mods I use to make a modpack that feels close enough to what I would consider a faithful approximation of a "what if scenario" where Valve and Mojang colaborated on a port to the Steam Deck.

If you have any issues or feature requests, go to the issues and feedback form and leave your bugs or requests there :)

The menu has a fresh new logo, a slightly expanded set of splashtexts, a skin changer (courtesy of SkinShuffle) and a button that adds a small window displaying some of the new features added through mods as if they're additions to the base game. This I will add to if I make further updates.

Most of the assets (logo, changelog panel, screen titles etc.) are custom made in Blockbench and Medibang Paint Pro, others belong to resource packs I have bundled with the modpack, primarily 'AmongstReality's OreUI' for a very well stylised console-esque look and feel.

The menu and loading screens use images in a slide show instead of a panorama, because I wanted this version to not only have a slightly more unique look, but also easily demonstrate more of the game than a single panorama would.

All loading screens have tips, trivia and random flavour text, 91 to be exact. These range from vanilla tips from past updates, tweaked ones to add parity with new features, all the way to completely custom tips for the mods in the pack like "Emerald Gearset" and "Promenade".

Here are a select few of the tips, trivia and random nonsense you might see when loading into a world.

Geophilic has been added for terrain generation. This provides a slightly more "Legacy" feel to the world generation, while still allowing for all vanilla biomes, including huge mountains and crazy caves, as well as new features of the landscape like rocks in forests, downed trees, and cool cliff faces. New Minecraft has such intense verticality that even most "flat" biomes tend to generate with massive hills all over the place, making an average adventure feel more like a parcour map or an endurance test. Geophilic strikes that balance of maintaining verticality and interesting terrain, with calmer areas ripe for a large build without too much terraforming required for a flat foundation.

Using "Brainier Bees", Bee A.I. will bee more consistent (sorry.) I've also included "Nice Mob Variants" to spice up the wildlife of Minecraft, adding even more mob variants than were added in recent updates.

Overall, the terrain and mob variety are far more interesting thanks to these mods and data packs, exploration is exciting again, and more stomachable than the near constant extreme hills of modern Minecraft world generation.

ShroomCraft

ShroomCraft expands the mushroom fields while still maintaining the vanilla feel of the biome, with new mushroom wood types, new mooshrooms and mushrooms, to spore bombs with unique effects for intense engagements.

With Serene Seasons, the world will change day by day. Every 8 days the season will cycle through early/mid/late seasons, then to the next one. This allows weather conditions to change across the world, and adds a unique mechanic to crops, where each have specific seasons they grow quickest in.

Friends & Foes brings back the Minecraft Live: Mob Vote losers back into the game. A terrifying Nether boss, a creature that hungers for dropped items, a mineshaft dweller who trades items, and even a magical ice sorcerer, there are many new mobs present that breathe new life to the world.
