As I have not played either game, I was not commenting on the game mechanics. I was referring to the fact that two similar games may not necessarily be allowed to have similar names if one were trademarked, which is the mostly the focus of the guy's complaint. Considering King's reaction to his complaint, I would say that King actually supports his claim but are using a clever method to get around it to use his own claim against him.

I agree that there's not much to be done, and should not be done, about copying a game's mechanics and attempting to improve upon them. But part of the accusations are cloning art assets which can have consequences up to a certain point. I think a combination of cloning art assets in accordance with their respective game mechanics should be an issue in this case, whether the law supports this notion I have no idea.
