Some mods, which make your survival mod a bit mor fun but also more complicated to play.
Use Immersive Engineering, Forestry, Ex Compressum and Ex Nihilo:Creatio to gather resourses faster and more efficient and even automise some processes.
Always know where you are with Journey Map.
Bulid more fancy tools with Tinkers Construct.
Tough as Nail maks your survival a bit harder with thirst and themperatur.
I orientated myself a bit on the Forever Stranded Modpack
