I bought it yesterday after waiting for at least one 'good' patch. I saw the Update 2's notes and thought that it definitely looked like the devs care about it, and that they're taking the game's support seriously. I had been interested by the game ever since I saw the first previews but I knew that I had to wait at least for some time, which I did. I think it payed off, because the Total War game I've bought is probably the best one in the entire series for me so far; and don't think that it's gonna get worse either. To be honest though, there's some bias. I've been dreaming about a Total War game set within the Warhammer universe since the first Rome. In fact, when I played Rome for the first time it didn't take much time before I started imagining those Roman and Carthaginian armies as Orcs and Chaos units instead.
However, after the absolute Total (see what I did there huh?) mess that was Rome 2's initial release (a game that I never bought, and to this day still don't regret) I think that something must have happened, either internally over at Creative Assembly, or at SEGA (or both, maybe actual communication is what happened, maybe the working conditions improved; maybe someone at SEGA woke up after Rome 2). So, I don't know what happened, but I'm playing a rather [surprisingly] polished, pretty well-balanced, smoothly-performing (even under the clearly-labeled "beta" DX12 mode), non-crashing, non-stuttering-even-at-Ultra-(and recommended)-video-settings Total War game that's barely three months-old post release (in fact, it'll be three months-old tomorrow on the 24th). Now, THAT is what of course should have happened with Rome 2. That's what actually happened with Shogun 2 (in my opinion, the second best in the series; now that I think Warhammer is the first).
I was still very hesitant buying this one but I'm very pleased to 'report' that I'm simply lovin' it. I highly recommend it. Really, good job CA; now stay on this track please (and SEGA, keep them there, don't rush their games out).
