I bought the digital copy and pre-loaded the game but didn't get to really play until the following day. My wife and I had our second child three weeks ago, Jacob, and he has been taking just about all of my free time lately, plus now that my paternal leave is over and I'm back at work, it's been hard finding time to play.
I have gone very slowly through the game so far playing Classic Hard mode, and I just finished the very second battle of the game (including the tutorial). I spent a lot of time talking to everyone in the monastery once I was free to roam around, and that took most of my time.
I'm terrible at strategy games such as this, but I am persistent. I had to restart twice during that second battle because I made input mistakes, such as telling a character to wait by accident, or attacking the target unintentionally. I wouldn't fault the controls, though. Great game so far; I'm enjoying it a lot.
