GT Horizons modpack is arguably one of the biggest and most complex modpacks in Minecraft's history. To start with, it is centered around GregTech, a creation that completely overhauls the game, adding in new machines, materials, and new crafting recipes for every existing item and mod.
This modpack adds the longest progression system found in any mod or modpack for Minecraft. It is speculated by some players that it can take tens of thousands of hours to complete every single quest in every stage through which a player has to go.
The modpack already has popular and complex mods like Thaumcraft, Blood Magic, Astral Sorcery, etc. What makes GT New Horizons special is that even though all these mods have different progression systems of their own, the modpack creators have somehow managed to weave every mod progression into one giant system, connecting them to one another seamlessly.
GregTech: Community Edition is a mod that is at GT New Horizon's core. It drastically changes ore-processing methods, power system, and crafting mechanics. It also introduces new stages through which players need to progress, starting from the Tutorial, Bronze Age, Steam Age, LV age, and then MV power tiers.
The modpack adds thousands of new crafting recipes, both for new and old items, more than 3000 quests, completely unique world generation, new combat mechanics, and more.
This modpack can be so complex that the developers themselves stated that it is not meant for new Minecraft players, and even intermediate ones who are new to the modding scene.
In conclusion, the GT New Horizons modpack is an entirely new game based on Minecraft as a sandbox. It adds hundreds of features about tech, magic, and machinery, and it has complex questlines combining the three aspects.
