The Meaning of Life, the Universe, and Everything.
My Room :P
First off, wrong section. Second off, 550+ mods is a bit much for any normal user to even start their world up. Third, I'm interested but I think you will run into issues, also if you could, please add a modlist, I'm curious what all you have running together.
Looks like you added everything you saw on the twitch launcher. Here's my critique: even if it loads, the average player is going to get extremely overwhelmed with the content, or won't even use 2/3 of these mods in their playthrough. I suggest focusing on an aspect you enjoy, ( tech, magic, exploration, etc. ) and narrow the mods down by a ton.
