It is mostly tech with some other random stuff. There are mods such as EnderIO, Draconic Evolution, Thermal Expansion, and more. There is so many different things you can do that this modpack will keep you busy for a while. It is not very tedious and is still extremely fun. There is lots of OP armor and tools that you can get with this modpack such as Draconic or Quantum. There are also different tracks you can take to accomplish what you want to do. You can do things the EnderIO way, Thermal Expansion way, or maybe a little bit of everything. Also, there are many small mods to improve your playing experience such as ore excavator and inventory tweaks. I made it to play on a server with friends and I hope you guys can enjoy as much as I will.
Make sure you go to settings in curse and minecraft and change it to boot from java instead of native.
