Worked as a programmer for them. The major point here is the possibility for them to deploy on a massive amount of different phones and platforms. Parent mentionned BREW and Java, but there's also Symbian, Blackberries, iphone, smartphones, and soon a lot of Android. They have some multi-platform framework making a breeze of this mess. From recent events of small teams with great ideas a la World of goo, I hope they will give make more concept games and give a lesser importance to franchise games.
