There was this interesting sci-fi board game I played that featured multiple alien factions... and multiple human factions. The alien factions each represented one race, while humans were divided. The lore of the game pretty much stated that humanity would overrun the rest if it wasn't divided by ideologies and infighting. Like in the real world. I think the space frontier will open and be going on for a good while before humanity abandons tribalism. If it ever will.
