I read somewhere, a while ago that games like Clash of Clans are really just payment apps disguised as entertainment.

On a somewhat related note, I tried playing Clash of Clans for a month and once the time to complete a building took too unbearingly long, i just became disinterested in the game and opened it less often.

Feels like there some variation of the law of diminishing returns, or at least a system suggested by the post that weeds out the patient and stimulates instant gratification.

Glad I didn't get addicted :)
