The one thing I do want to mention is that there isn't a way to easily get yellorium other than quarrying half of Mars. They're aren't any yellorium bees, either, so the only option would be Laser Drills, but since MFR isn't in the pack, no Big Reactors for me! I'm saying you can still make it that to even get a Laser Drill requires going to the asteroids by requiring for it to need titanium, and just the sheer power required makes it a far end game item. Also, without Laser Drills, what's the point of Big Reactors? Half the reason anyone does the mod to the end is to get Laser Drill power. Otherwise they'd just use charcoal power or something the whole game. Laser Drills, in of themselves, makes people want to upgrade their power structure to be able to handle something so power hungry, but still so useful. What's the point of making a 29kRF Big Reactor Turbine if nothing needs all that power? There's no point then, it would be a waste of time and resources. Bees may be able to make some of the ores, but without MFR, Big Reactors is almost useless.
