This mod gives considerable improvements in how AI grows its civs, and how it manages moving large number of units into attack formations. it definitely speeds up how civs develop in early game, making immortal games feel almost like deity, however this mod is hampered by serious issues.
I have never seen AI building city walls, or improving strategic resources, and therefore not building special units. Therefore the mod feels great at the beginning, but then it falls flat and is almost unplayable.
Half the AI civs end up in constant war between each other, even though they do not secure strategic resources with improvements, therefore never building swordsmen, which enhanced by the fact that they never build walls makes their cities very easy to capture.
