Just to outline some differences between the Stencyl version and the separate extension when our version comes.
- We're only supporting bottom center and top center positioning to keep it consistent with the iOS version. Through code, though, it should be possible to use those alternate positions should you need them.
- You'll input your AdMob Publisher ID inside Game Settings > Mobile > Monetization as well as the ad position.
- It follows from that that you will not have to make a code call to initialize the ad system. The initialization happens automatically the first time you call 'show ad'.
