As discussed in my Monetizing Children paper, the ability to weigh this short term pain relief vs. the long term opportunity costs of spending money is a brain activity shown by research to be handled in the pre-frontal cortex. This area of the brain typically completes its development at the age of 25. Thus consumers under the age of 25 will have increased vulnerability to fun pain and layering effects, with younger consumers increasingly vulnerable. While those older than 25 can fall for very well constructed coercive monetization models, especially if they are unfamiliar with them (first generation Facebook gamers), the target audience for these products is those under the age of 25. For this reason these products are almost always presented with cartoonish graphics and child-like characters.
