Guys,
Force quit ensures the following:
1. Our medals won't increase as a result of defensive battles.
2. Resource production by roads, caravans, farms, mines, etc. will be matched or outpaced by looters and failed attackers who force quit. (We lose resources, reset traps, renew blessings, and ironically, the traps and blessings actually hurt us because they kill the first attacker, and then make subsequent defenses less effective.)
This ensures that we will have to be constantly playing to advance.
This all has to do with daily active users and "stickiness". Having people constantly play the game leads to a higher likelihood that each account can be converted from a non-spender to a spender. This is called conversion.
Anyway, a large number of daily active users = lots of money.
Enough from me. Just feeling a bit cynical. I wish they would focus more on providing a fun game and less on frustrating us into spending.
