At the moment, I'm using just GregTech 5, IC2 (since it's still required for GregTech), and AE2, plus utility mods like NEI and Waila, in single-player peaceful, and I'm somewhat daunted at the moment looking at the recipe for the "basic" steam turbine (I've been playing this world for about a week, I've set up 4 small coal boilers powering 5 bronze steam machines, and I've got a bronze plated blast furnace and a high-pressure coal boiler that I'll be using to supply steam to the turbine). Now I'm wondering about how other people deal with this, so my questions are:
1. Does anybody else play GregTech in single-player?
2. How many mods (not counting utility mods) do other people use alongside GregTech?
3. Is it more common to configure other mods to try to balance with GregTech (beyond just disabling oregen), or to use them to soften some of GregTech's difficulty? (e.g. using Railcraft tanks (or maybe Extra Utilities drums) to store steam, using Buildcraft pumps and pipes to supply the water to the boilers, or even using a Tinkers' Construct Smeltery for the early metals like iron, copper, tin, and bronze - I wouldn't expect the smeltery to handle all of the GregTech metals, even after compensating for the Aluminum/Aluminium spelling discrepancy mentioned on the FTB GregTech mod compatibility page)
Note: I realize this thread might fit better in the GregTech subforum, but I don't get a "new thread" button there (not sure why, or even why the GregTech subforum is still under "addons" when it has become more of an overhaul than an addon). I didn't want to ask these questions in the main GregTech thread, because then replies to my post would likely get buried by other posts in that thread.
