Space Quest

50 years after the Zyccer invaded, earth has adapted to deal with alien threats. We took their technology and reverse engineered it to be usable by us humans. 100 years after we have made the jump into cross-system travel, and 150 years later we have accomplished warp-jumps. Now 200 years after the initial Zyccer contact, humans and alien species have started to integrate. There is much less hostility towards most of the known races, though some are still set in their ways. We know there are hostile aliens like the Zyccer out there, but we have not made contact with them yet.
