I guess this will differ according to each type of game. Thought it would be could do get some thoughts on this.
1. A number of games only shows iAds in the Menu Scene
2. A number of games shows iAds through out the game
The game I'm busy with I think it will be difficult for an player to click on an iAd during game play. Thus considering only having an iAd at the menu, when a game is paused or when the player has died.
