No, there was the OA age at first. Then came the w00t, MCD and whatever age. Than the -JG- and AF age. Then UNSF became a huge powerhouse as well. And those were the last tribes who were strong enough to shake this world on their own, and they could beat any tribe they wanted to. Now there's the LIFE, TBP and GX age, in which all are equal, and none are feared like the big guns from the old days were.
