Eight tribes? Maybe you are an 40 year old edgelord like myself and want to play as a doomsday cult to destroy the world with nukes, gas and luxury limos? Want an easy time? Pick the cyborgs with their OP units which you can make even stronger with armor, or why not use their tanks to just win? Not into tech? Go with the Amazons and show the world why feminism is equality and why all men are pigs that should be stomped until they worship you like the goddess you are, or go all out with bikers and their mighty flying bike and bribes, still not satisfied? Rule law and order as the Enforcers, they got everything and nothing (because it's all super expensive and requires expert gameplay, are you that expert? Then you should rule with jet powered guys that fly over bombs mines and rivers, troops that freeze you, troops that can go invincible, vehicles that crush terrain and destroy mines and everything bad, and much much more, then they run out of ammo and you got nothing you paid a fortune for, also they have super range but are terribly weak) then you got the trailer trash with their awesome Elvis inspired music and cheap units, just buy pigs loaded with explosives until you win with minus points because of all the cheap pigs that went boom lol or go with tractors with flamethrowers and Molotov cocktails, life's cheap yet easy for the trailer trash, lastly you can't choose but still capture the "poor" civilians and pump out their units, they have no vehicles but a bunch of cool heroes that for some reason took the side of the weakest people; Luther, Clint, Vladina the flamethrower (or something I forgot her name but but...)
You don't build units, you click a button and they spawn, likewise you can take over buildings by killing everything inside and entering it, if it weren't that this game has a bunch of ugly bugs it would be one of my absolute games of all time
And still, it's not far from the AI is dumb but the game is fun regardless, also each tribe has heroes
