For everyone who wants to throw giant Ape poo at people. Or blow stuff up.
First off. The people in your tribe are good smattering more intelligent, while they -don't- construct buildings on their own, something that was handy in the first game, they instead stop breeding like rabbits when they're almost out of living space. They'll mine, farm, tend to livestock, and cut wood more adeptly than the original... oh rather than the first time round, they won't deforest the entire swath of woodlands nearby, rather they'll rotate where they cut from, so that the original choppin' ground has time to regrow.
They'll only go nuts on livestock and grain when there is a food shortage.... and lets not forget ARMIES! With the addition of the Creature stomping, lightening, and fire balling every enemy in sight.
The idea of building impressive cities rather than throwing rocks, sending flocks of birds/bats, and setting nurseries on fire to convince other cities to come believe in you is fantabulous, along with the tribute system, and the easy access tab for miracles, that lets you stock up multiple fireballs for a fireworks show... Holy crap.
I'm normally long winded, but with this, all I need to say is: Play the game. You will feel joyous.
