It definitely pushes some 360 owners to Windows Phone, but I don't know if it's all that many in the end. I mean, statistically relevant in the grand scheme of things. If makes a dent, for sure, but I'm not sure if it's huge. With that said, I'm interested in getting a Windows Phone and I happen to be a 360 gamer. But I wouldn't say it's because of the fact that I own an Xbox 360. It plays a small role, but that's about it.
I like it. I've played a ton of it, that's for sure. It has become a little boring, I do have to admit that. I'm hoping the Crimson pack will liven things up. They need to add forge maps as well. And add more fun playlists (rockets, etc).
