I never claimed the game was perfect, I only talk about my personal experience which is so far pretty excellent, and already more enjoyable than Shogun 2. The menus don't bother me that much (although they could be better).
Armies and Recruiting function much differently (and better) than they do in the other Total War games. Recruiting directly into your army is different than building and then moving units from towns into your army. You don't have to lean on the turn button to get your army together and you don't have a smattering of individual units running around everywhere. It also puts the focus on the army itself.
Secondly the Provence system is fantastic. Groups of cities working in concert and sharing bonus, while at the same time simplifying the interface for building construction was a huge step in the right direction.
3rdly, performance for me is overall better than Shogun 2. I have a brand new computer with an SSD and battle load times are significantly faster than they were in Shogun 2. Now, turn times are longer overall but faster per faction. That is the price for having a much larger and more diverse map, one I am actually quite happy to pay since that was my biggest gripe about the last game. I am actually not looking forward to them "optimizing" that part because "optimizing" the decision tree for the turn-based AI means pruning decision branches earlier and will result in a dumber strategic AI, plain and simple. There is no way around that one, turn-based AI is still basically the same as it was in the 70s, a brute force decision tree algorithm.
I also tested some skirmish battles against the AI, I set up identical armies and played the AI at normal and very hard difficulties. I trounced the Normal AI, but the Very Hard AI beat me twice (I am a distinctly average player). I could probably beat it after another try or 2. But overall the AI did the right things, matching the right units against their counters and running the cavalry around to smack me where it hurt most.
Normal Difficulty
Very Hard Difficulty
Now, at the same time I am trouncing through the campaign with little to virtually no challenge (turns are still under a minute though), even after upping the battle AI. Near as I can figure it out it is probably one of or a combination of roughly 3 reasons:
* Roman Units, especially early on, are simply much better than the other factions.
* More complex levels screw up the AI (skirmishes were on a simple mostly flat map).
* Ok, I had a third one but forgot what it was
So, call me a "shill" if you like, it is as pointless as me calling you a "bitter harpy". I like all of the improvements more than I dislike the drawbacks (most of which are quite fixable), and am looking for ways to minimize those drawbacks so that I can enjoy the game better. You are welcome to ignore me so I can have actual fruitful discussions with people in the same boat.
