It has something for everyone. Machines, better caves, Bioms o' Plenty, etc.
Kai Jurvival mainly focuses on user experience. It adds a lot of little Mods which are creative, but aren't extremely huge. (with some exceptions). Caves, the Nether and trees are optimized to be more interesting and more beautiful. (like adding biomes to the Nether,
stalactites and stalagmites in caves, more creatures, better models, little stones and branches on the floor, quarry's, etc.) Exploration is so much more fun with Bioms o' Plenty and Mo' Creatures, quarks, better nether and other well known or even unfamiliar mods, like Yoyo's, Volcanite Ore, CrapMod9000, The Cactus Mod, A Crude Start and so on.
The goal was a fun Mod Pack with no Mod in clear focus and I think I achieved it quite well.
