I am looking to make a more challenging environment for MC 1.8, was wondering if there were any mods similar to Enviromine, Glenn's Gases, Weather & Tornadoes, Hunger Overhaul, Iguana Tweaks, etc.?
So many mods, so little time.
There's not many mods like that regardless of your version and 1.8 has few mods avalible anyway but you may like this.
It's all I could find that doesn't add mobs or change their difficulty. Hopefully others will have better luck. On the plus side it does make it more realistic.
