Kazucraft is a modpack that came to me in a dream, and it focuses on Industry, Exploration, and Multiplayer Interactions. It tries to appease most players with something they may like, which resulted, despite best optimizations applied, in rather high requirements to play comfortably, most notably the 8GB of RAM as recommended memory setting.

Features:

Create with various addons, most notably The Factory must Grow and Creating Space.
Immersive Engineering with addons for those who might dislike the Create.
ComputerCraft and Applied Energistics 2 for those who can utilize them, and completely optional too.
Timeless and Classic ZERO for those tired of new combat mechanics, with integrated Create ammo creation and Loot cases via FTB Quests.
Warium, for those who like warfare and more technical mods.
Valkyrien Skies with many addons, such as Valkyrien Warium and Clockwork, for building vehicles, and utilizing them.
Ice and Fire, Cataclysm, Mowzie's Mobs, Iron's spells 'n Spellbooks, Epic Knights and Tinker's Construct for those who want to stay closer to melee weaponry, or want to deal with some magic.
Rechiseled, Macaw's Various Mods, Chipped and Domum Ornamentum for Builders.
Regions Unexplored and Aether with various addons, for those who want to explore the world.
And many, many more that i would spend all night mentioning, so find out for yourself!
