Maybe. I have to admit, that I'm not even casual gamer. I'm a developer to. Doing software is my favorite game. So a game must be very interesting, kinda good looking (this could be anything from pixelart to highly realistic) and short-lived. iDon't play games for a long time. After a few days I start looking for something new. And browser based games tend to be all nearly the same. At least for me.
