So, I decided to give Rome II a try with the Total War free weekend and I have to say that it's god awful. I turned off the game after like an hour.
The first thing that pops up as you turn on the game is the massive DLC shoving. Half the options in the main menu are locked with a little "would you like to give us some more money"-button. The game's graphic setting were set to ultra as default and the game still looked like shit. The texture quality felt like it was worse than in Medieval 2. And even then the game lagged like hell.
The game still has the same AI issues that every Total War game has. Units get stuck all the time, especially in cities. When engaging in a melee your units just go towards the enemy in a single file and the best way to make your units properly attack is to tell them to run through the enemy (which obviously causes you to take more casualties because your guys aren't actually fighting). When charging towards the enemies your units tend to clip and slide among the enemy ranks. In addition, trying to keep any coherent formation is pretty much impossible and it feels like you constantly have to be reminding your units what formation to use after every move order. This is probably why Empire Total War is my favourite, as the formations are much easier to hold and most of the fighting is done at range.
I do appreciate some of the finer details in visuals like arrows sticking in soldiers and shields but overall Rome II feels like a really rushed and broken project. I didn't try Attila at all, so I don't know if they made any improvements in the newest game.
