I really love all these new updates, but I feel that the Windows Phone department is really kind of lacking. As of right now, iOS, Android, and Amazon versions have been updated consistently up until a week or two ago. The last WP update was over nine months ago. I'm sorry if I seem a little judgmental, but it's not very fair. Also, the different mobile platforms should really be compatible. You pretty much have to have the same exact device as someone else to play co-op, because updates are rarely released for all platforms and within the same time frame. Mobile's great, but being so far behind other platforms really discourages playing.
