Crush the Castle 2 is one of those games which you can play again and again until you get bored. The problem though, is that you do get bored, which can set in sooner rather than later.
When I initially played Castle, I thought the game to be addictive. This was partly due to my replaying completed levels with an intent to improve or even perfect my overall score.
However, returning to Castle made me realise that this game wasn't addictive, but in fact had high, though not lasting, replayability.
