I'm not sure what the fuss is about. Graal already had good reviews so it's not like it is trying to counteract negative reviews. Just when you update an app it starts you with a new slate so the idea is to get people reviewing. Also I'm pretty sure the term "great" refers to the quality of the review, not of the game.
Also anyone using this as a basis for how often graal gets updated is being stupid. The app itself doesn't need to be updated to deliver new content. "lol this just proves how little the game gets updated when is the last update? Years ago!!!" What about castle, house templates, capsule machines, box fort, state contest(and new system)?
