Can't lie, I think a mobile game isn't the way to properly gauge interest. It would be better if they released the previous four games in a collection with a gallery for the game's artwork, a jukebox feature, Online, etc, etc. I also don't know that a lot of people who actively play mobile games would be able to add an AW game to their already sizable plate of other games they need to keep up with daily. With a collection it makes it easy to catch up and familiarize yourself with the series as well as letting veterans (Or people who got into the series during the current drought) finally be able to show their demand for a new entry in the series with their wallets.
Just my thoughts, sign me up as a supporter please.
