...Orph, how the hell do you gigure that the Magisters have access to more resources than the Mechera? As you said, you have access to a few suns within one galaxy that you're tapping into. The Mechera control another dimension pretty much completely. I THINK the Mechera have a larger pool of resources. And you dont HAVE a few seconds, thats the thing. With as many Mechera there are, any holes you make are going to be patched pretty much immediately. Not literally immediately, but you get the idea. Its pretty much a matter of miliseconds.
Alright, fine. They can merge mentally with computers. Weeeell, see, thats pretty much LIFE for a Mechera. Also, I should note that while they've been Mechera for at least a few millenia, their space program was six centuries ago. When it began, that is. Prior to THAT, they'd been focusing on how to advance themselves, their computer systems they live in, their very code. If they can achieve all that they have as far as spaceships and interdimensional travel in the span of a few centuries, while recovering from the loss of their homeworld to a supernova I might add for the later few, just imagine how fast their advancement of new technology would be. At that rate of progression, they have been bettering their computers for at minimum two thousand years. Thats how evolved their hardware and software is, and they are still advancing. However, the reason I didn't want to get into that is because as good as our Empires are in these respects, we have no way of comparing them without it, at some point or another, devolving into a 'whoice has the bigger e-peen' shouting contest. The Magisters are intelligent, I wont deny that for a second. But by any and all means, so are the Mechera.
And fine, either way. Point is your OHKOing a Titan. You get the idea.
