If the humans gave many of the other races the hyper-drive technology, then why do you not know about them in the game till you run across them again? Its like "Hello, here is the technology that will allow you to travel among the stars, see you later"
Or why are some civs pissed at you from the start? I mean you gave them a free tech!
One would think that if we gave them something that would enable spaceflight that someone would send a message back to Earth, saying that we found aliens. And why are there none of these scout ships that traveled around and gave the hyper-drive technology to these other races?
