The Gerflargle pack is intended for a casual playthrough with friends. The focus is mostly on tech(Mekanism, Thermal, and Crate) but does bring in some fantasy(Ice and Fire) and magic(Eidolon) mods for those who want to branch out.
The pack has minimal adjustments to mods and has a fair number of small tweaks for quality of life. There is no "goal" apart to have fun and experience the mods as they are and have fun in your own way. I guess this means its a little bit of a kitchen sink pack.
There are some adjustments to control ore spawns and reduce duplications of ore types, and has the ability to adjust, add in, or remove items/recipes to fit your group's/server play style.
