Eh, like a week ago I started my first ultimate world. First time playing with Gregtech as well. I hated it because of the steel changes. But now I love it, because I still have so much to do because of all the new steps I need to take to build even the simplest of machines.
Diamonds for macerators? Genius. I actually had to go caving for quite a bit before I was able to set up a nice ore doubling system ( I didn't want to use TE or Quartz Grinder at the start, I wanted to figure things out with GregTech ), not to mention the need for advanced alloys forced me to build a rolling machine very early.
Then there is the steel for the next level of stuff. What I did was, I figured one furnace wouldn't be enough. So I went and found a swamp for the slime balls and a nether fortress ( which you need for bricks anyway ) supplied the blaze powder. I've built 6 railcraft blast furnaces. That's a lot of coal coke or charcoal you'll say. Yes! Because of that, I made only one coke oven ( primarily because of the need for creosote for the next step, but could be done without if you've found an abandoned mineshaft for the tracks ) then went straight for a SC2 tree farm. I was collecting wood that automated to charcoal and saplings and apples will help with the biofuel later.
That was all because of Gregtech changes, and I like it for that. Much of my time was spent without a goal, but it defines the next step, so you have something to do while thinking about your next build or system.
