I work with 20th Century Fox NZ creating games for movies, I have been developing full time with Unity for a year, and have created many projects for IOS, Android and PC (including Kinect). I will also include free marketing and social integration into the game as these are deemed essential for the success of the product.
Due to the nature of Unity it will be easy to create a game for all mobile platforms. Mobile games require easy to use controls so that will be where a lot of work is put to make sure people of any skill level can play, but it will also be advanced enough so to keep people coming back for more.
