An ever expanding modpack of mostly things that I like (mostly tech mods).
The pack was built originally as an enhanced vanilla experience, with many mods to improve quality of life such as JEI, JourneyMap, Tomb Many Graves, HWYLA, Morpheus and of course, Toast Control. Even ignoring all the content-heavy mods, the game is now improved mechanically and much nicer to use (and goodbye annoying pop-ups for every new recipe you uncover)
After improving the vanilla lifestyle, the pack has been built around technology and automation. We have Mekanism, IC2, Immersive Engineering, Industrial Foregoing and Ender IO to name a couple of the mods that will allow your technological empire to expand. As for the classic problem of having too many tech mods (about 8 different types of each ore), Unifier comes pre-configured to ensure your inventory is as clean as possible.
(Full modlist coming soon)
