1. The battle feels more like an RTS (ex: Age of Empire) than a realistic battle simulation. The units run around like flash on crack and they have not even a slightest idea of what a formation means (yes, even the roman cohorts).
2. Graphic/CPU optimization is just horrible. Way worse than Shogun 2. I know I don't have the best computer/GPU, but, if I'm able to run Shogun 2 on very high/ultra than I should be able to run this at at least 'very high' setting. And BTW, the high/very high setting in this game is 100x worse than Shogun 2.
3. Overall the game just feel too simplistic, yet, it's also confusing at the same time because of the complicated, multi layered UI. The Navy has been rendered useless because now units could just walk on water (magical transport ships, yay!). If you play a faction like Carthage which, historically, depends on their large Navy to control the sea to protect their empire from Naval invasion, your Navy is useless. AI could just pop up anytime, anywhere and invade your coastal cities without having to build a Navy which is just ridiculous.
IMHO, this game is an insult, a slap in the face, to all of us veteran total war players. It's obvious that CA made this to try and bring in new players who are more used to arcade, first person shooter type of game. Shame on you CA, shame on you.
