You can exploit the weakness to help people in another way. How many of us grew up and mastered arithmetic with Math Blaster or similar?<p>Gasification works and exploits a human weakness. Incorporating it into a game like many mobile games (FarmVille) just wastes people&#x27;s time and encourages them to spend money on meaningless tokens and trinkets that will literally disappear at some point (as opposed to the still silly and useless trinkets you might get from an arcade prize shop, but at least those you can keep). Incorporating it into something more useful (or at least with a more valuable output) is a good start.
