Not really.
iOS gaming in general isn't very good in my opinion, due to the control scheme.
I do play games on my iPad and iPhone, such as Peggle, GTA Chinatown Wars, Where's my water and a few others, but anyone that takes gaming seriously will use a PC, Xbox 360 or PS3. The gaming experience on those machines are clearly better than anything iOS is capable of.
iOS gaming isn't even close. Games in each genre have similar limitations. For example instead of open world characters move a short distance and stand in one place. For really basic games it's ok.
