&quot;mainly built around in-app-purchase mechanics&quot;<p>In-app-purchase mechanics is awesome for Amazon delivering stuff to my house, listening to music, watching videos, kickstarter type support.  As the root of atari2600 level gaming experiences, it doesn&#x27;t work well.  Once you condition people to sit on the couch and spend small amounts of money online, don&#x27;t be surprised when they spend it on movies, music, pr0n, amazon stuff, instead of the intended &quot;we wrapped Frogger in an in-app-purchase skin, now give me my entitled billions&quot;.<p>If I&#x27;m sitting on my couch in the mood to blow money on worthless stuff, almost anything I can buy provides better return than IAP games.  So in a supply and demand sense either games have to get better (good luck) or cheaper (good luck) or they can collapse down to the point the survivors can do better or cheaper.  Or games have to find a way to destroy online paid shopping &#x2F; video &#x2F; music.<p>There is another aspect of free hit where a new tech like mobile gaming gets a free hit... for awhile.  Now its not new anymore and they (as an industry) can&#x27;t survive, well, that&#x27;s why they&#x27;ll go away.<p>Nobody is making money off Pixel Dungeon and its forks.  Oh well, good luck stopping them.  I think they&#x27;re a lot of fun.
