I'm the "extended market", that is to say, an over 40 gamer.
There are a few mobile games for smart phones that work for me. Mostly match three games.
I've decided to stop buying mobile games as the majority don't have the depth or controls of console games.
Majong and Bejeweled, sure, I'll play on my phone .. but a platformer, racing, RPG, game I'm playing on a dedicated gaming console. YMMV
