I'd say the "higher end game apps" are PDK apps, often because they're just porting existing iOS code. They have no need for the HTML UI. With OS 2.x there are now options for hybrid apps as well - native code, but HTML UI. And the option to do backend work as node.js based services. Essentially they've got a great mixed model depending on what you want to build. All HTML/JS in the app. Or abstract backend services but still code in js (node.js). Or ditch all that and write a native code app with its own custom UI. Or write a native code plugin with HTML UI.
