I know this is a tad late, considering, but I have to ask. Let me preface this by saying I haven't really gotten far enough in the game to really have AUTOMATIC EVERYTHING. In fact, I usually get to a Buildcraft quarry and then go "... WELP TIME FOR A NEW WORLD" or something along those lines. I usually don't get a huge fancy base, or if I do, I don't have a bunch of buildings for different purposes. So, my question is: Do you end up getting more metal than you know what to do with, and that's why you made metal blocks? I know the factory blocks from chisel are relatively cheap, but that silver pipe made of silver blocks makes me gasp. "How does he have that much metal??? Maybe I just haven't been playing long enough..."
