Copyright is such an amazingly profitable concept.  Just how profitable it is just really blows my mind.<p>I had a friend who created one of the early, best-selling games on mobile.  Early into his success I was like, &#x27;Your game is awesome.  I see people playing it every day on the metro.  That&#x27;s crazy!  But, if you&#x27;re smart, you need to turn that game into something iconic.  You need a &#x27;character&#x27; that will lock those players into a cultural experience.  Trust me: your game will eventually fade, but that &#x27;character&#x27; will remain - and you&#x27;ll literally make millions on the copyright for 100 years.  And, you won&#x27;t even have to do much to maintain it.&#x27;<p>But, instead of creating their own iconic characters, they opted to license other company&#x27;s iconic characters.  Now, years later, the game has much fewer sales (as expected).  And, I&#x27;m not sure how much revenue they&#x27;re making, but I&#x27;m guessing it&#x27;s not much.<p>I&#x27;m not in the game development business.  So, I don&#x27;t know much.  But, when I get a chance to talk to game developers, I try to stress the importance of the cultural experience.  The game play will make or break a game, sure.  But, if you have the copyright on that cultural experience - that will generate revenue for forever.
