Are most games on the IPhone done with OpenGL ES?

Question

I was just wondering if most games on the iPhone are done in OpenGL ES as opposed to using Quartz and Core Animation. Are Quartz and Core Animation mostly used for just creating slick interfaces? Or if there is a point with games where OpenGL probably has to be used over using other tools?

Answer 1

For efficiency reasons OpenGL ES is you best choice for games, unless your writing a "simple" board game or card game (like Solitaire). In this case Core Animation would be a good fit.

Answer 2

You should check out cocos2d-iphone if you are going to do a 2d game. It seems to be a pretty solid foundation. It comes with the chipmunk physics engine and everything all ready to go.
