Beyond Reality on AT Launcher. Well, you did ask, and I'm being honest as always.
FTB Resurrection just isn't what I'm looking for in a GregTech modpack. BR is a bit difficult, for instance, I currently cannot figure out what pickaxe I can make so I can mine obsidian so I can get to the nether so I can progress my game. I'm stuck, in other words. Stuck in very early game. Not fun. But it IS fun! I'd rather play a hard modpack than an easier one (but not TOO hard)... and Resurrection seemed too easy, they didn't keep GT on hardmode. BR seems to have gotten it mostly right IMO.
