I got burned out by the MV era because I barely figured out how to do energy generation and I had no idea how to start oil processing. It's fun autism, but it's an extreme dose that only the greatest autists will manage to go through. Though I wish there were tech modpacks that have a similar guidance and complexity of GTCEu but using conventional tech mods like IC2 or Thermal mods. Plus some magic and world exploring mods for a complete modded Minecraft package, something for everyone. It's always fun when you get a few people to play a modpack like this and everyone does what they want to do, be it tech, magic or exploration.
Unfortunately a lot of those mods that add both tech and magic and a lot of world exploring with a detailed questbook which engages you in the modpack like MC Eternal also include Ice & Fire which is the absolute worst mod to add because it will drop a fucking endgame boss randomly in the middle of the map as you go exploring in the early game. Whoever likes that mod can go fuck themselves, I'd say it would be acceptable if all the hardcore mobs spawned like 10000+ blocks away from spawn so you'd have to travel a fucking lot to encounter them, leaving you a ton of space to explore without risking dying in five seconds and losing everything.
