Inspired by FTB Revelations and utilizing the mods available for Minecraft 1.16.4-5, Mountains to Valleys seeks to offer a wide array of mods while staying light enough for most modpack capable computers to run. Though the scope isn't quite that of a kitchen sink style, sky line to bed rock spanning modpack, Mountains to Valleys seeks to give players as many paths to travel in varying difficulties as possible, with as little overlap in each mod's mechanical feel as feasible. Additionally, a number of mods have been included to offer extra dimensions to explore including the Undergarden, the Bumblezone, and Space-Bosstools. For an additional challenge disable natural regeneration for your game world and use bandages and sleep to heal instead.

Notable mod substitutions include:

-Mekanism and Modular Powersuits to replace industrialcraft and some of buildcraft's mechanics

-Productive bees, Buzzier bees, and etc. to replace as much of forestry's bee breeding system as possible

-MoreRed to replace the redstone logic gates of Project Red

-Ars Nouveau, Mana and Artifice, Eidolon, and Nature's aura to try to capture as many mechanics of Thaumcraft and Witchery as possible

-Macaw's mods to replace Biblocraft with a wide variety of decorative blocks and furniture

-Refined Storage and addons for it to replace Applied Energistics
