Haha, this venturebeat review is an awesome example of people not knowing what they're doing.
Zulu asks you to declare war on Egypt. You say sure, ten turns, you then amass troops at Egypt's border and promise them you won't attack them. Two turns later, you DO attack them, with the Zulu, and the super honest and honorable Zulu now hate you because you've proven yourself to be a lying sack of s***. This strikes the reviewer as flawed. But wouldn't it be weirder if the honorable Zulu hate you for lying, except when it benefits them? This isn't a flaw of the AI system, it's a shining example of the AI leader flavors functioning brilliantly.
Also, city spam is and was always the best strategy? Religious bonuses are tiny and don't affect the game? And yes, he actually makes these claims for G&K, not just BNW.
AI military being irrational/horrible is a given, but this is just about the only useful part of the review, a confirmation that no large progress has been made to land combat AI.
This review should be caveat-ed beforehand with: I hated Civ V, and G&K, so I didn't play much of it, didn't find it fun, don't understand how the game works, and yet I will gladly share my uninformed and mostly factually inaccurate (not just opinion) description of it online anyway. ::shakes head::
