Every aspect of a design's product is influenced by the perception of others. That is why it is important to take in to account of the perceptive inputs of others whether your game is stepping on others tails, provoking unnecessary issues. To an extend, this is a cautionary rule for designers to adhere to. Failing this will sometimes put you in situation like copyright infringement, lawsuits and bad media press.
For an example, a new game studio is creating a game targeting the audience of its competitor. So they proceed in taking inspirations from their competitor's intellectual property. As a legally founded new game studio, they understand the importance of respecting the intellectual property of others to an extend.
By keeping the asset designs almost similar but with some details of mechanics or visuals the same, that the audience perceived it as an alternative game to play, they expect to be able to tap into the market of their competitor. Unfortunately, the audience perceives this game from this new game studio as a copycat, leaving bad press reviews stating it was a blatant rip-off.
Now this is where the new game studio should have practised the cautionary perception design. If the audience can perceive the new game studio's game as a copy, there is no say if it would lead to lawsuits or bad reviews. All these because of a disregard to other's perception. Not just using mere common sense, but an effort that requires collecting feedbacks and making wise decision.
