For the people who genuinely thought that the Grox empire was an empire trying to protect its species of the Milky Way galaxy, well, allying with the Grox will anger everyone in the galaxy, the Grox empire attacks other empires at random, without reason (none that I know of so far)
this makes a lot of sense because no one knew what were the grox but now you told us by taking your time in spore (or used cheats) great job and its nice to see people who never gave up on spore
Years late but I think that Steve's race was very violent, and they attacked earth, which got the attention of other empires. His race then attacked cus they didn't want any witnesses. They were overpowered by the other empires' combined forces, and fled to the center of the galaxy. The grox in their path however blocked them off and killed all but Steve, who made it to the center and hid in it with the grox territory as his protection, being scarred by genocide and karma, he decided to change his ways and became a creator of life instead of destroying it.
To be honest I think that some sims at still alive because the alien sims mite have herd about the grox plan to cause extinction to the human race so the alien sims just took a few humans and leaving the unlucky ones to be killed since that they had not much time
