It's a tough balance to strike because we want to reach a new audience. We want to get to those XCOM fans who may not have played Civ because history wasn't their thing, or strategy gamers that are playing a lot of these strategy games on IOS, that haven't tried Civ before. We want to reach those people, so we're trying to make the game more accessible for them, but also catering to our hardcore fans. We think a lot about 'oooh, what would they think if we took this out and put this in'. We try to listen to that, but we really want this product to stand on its own, and we've taken some risks, and made some changes that are surprising I think to fans, but I really think that they'll like it. David and I are relatively young designers. This is our first big Civ product. We've worked in Civ a little bit. We've done our time on Civ stuff, but it's really a testament to Firaxis to trust us and let us take this chance and make this new thing.
