I've been building up my world with all that Technic has to offer, and I just recently created a nuclear reactor and got it up and running. The problem is, I'm not really sure what to do now. It's great having a sustainable amount of power, but I don't really need it as far as I know. The only thing I can think of using the power for, other than furnaces, macerators, etc., is more quarries, but since I have a destruction catalyst, along with a dark matter pickaxe, nano armor and jetpack, making more quarries seems useless. Is there more to industrial/buildcraft that I'm missing or have I progressed to the end? What else can I build?
