played around with extra utilities generators. I'd say, the pink generator + that hardened clay biome I found recently... would give a nice energy source, the food generator accepts rotten flesh (but not TiCos jerkys), and the maybe strongest generator (but more or less okay): the heated redstone generator. it gives nice quantities of power out of molten redstone, and since I have quite a lot of that stuff, it is a nice way to power a quarry or something like that.
and there is the TNT gen... since I like to hunt down creeper, and I can even craft gunpowder out of several sources (lots of sulfur and niter can be processed automatically).
