Pitchford told VideoGamer: "As far as first-person shooters in general go, I found an analogy this morning. I've been trying to think about that, and I've found an analogy that really works: it's kind of like going to the ice-cream store. When you go to the ice-cream store, you want a lot of flavours. Every restaurant in the world, if they're just going to have one flavour, they're going to have vanilla. But if you eat a lot ice-cream - let's say you're eating vanilla every night - you're really grateful for rocky road! You know what I mean?"
