EA on Friday unveiled an additional stage of Spore, it's upcoming evolutional civilization simulation, offering potential players a glimpse into the tribal stage of development in the game. During the tribal era, players focus on building up their own creatures' civilizations while either conquering or befriending those of their neighbours. Players can design the tools and buildings their civilizations build, further customizing their appearance and behaviour.

If players train their denizens to conquer other tribes, then they will show increased hostility, fighting amongst themselves or playing rough with eachother. Players can also choose to work out friendships with other tribes, which will also reflect upon the tribe members, as they occupy their time with discussion.
