Nice! I'm hoping to beat the game as well on this playthrough. I think this is my 5th attempt? 1st game I gave up once I realized mega-plan was not the right approach for this game, pretty early like just after oil. The other 3 died off somewhere in aluminum; one save, I built a huge aluminum processing facility, but after I fired it up found a bunch of critical issues that would basically require a full rebuild. Save dead.
My current save, I've finished building my aluminum processing center, I'm going through the arduous process of building the logistics around it.. but I'm almost done! It's enough to process all 6 pure bauxite nodes with OC'ed MKIIs, hoping it carries me through the game but shouldn't be terribly hard to expand if needed.
