I wanted to try terrafirmacraft for years, so at first I tried technodefirmacraft. It was great and I got to the end of tfc and beginning of immersive engineering and pneumaticraft. However, once I was kinda forced to use rockhounding chemistry mod, I was thrown right off. Never in my life have I seen such overcomplicated mess of a mod.

Thankfully, I then found allthemods gravitas, which is better in every way imaginable.
