14 is more popular than 13 now, and almost everyone who's updated agrees its a better game now. The issue was when '14 launched as a new app, 2013 was still getting 3x the downloads just down to its position in search results, but in far fewer downloads '14 was being unlocked in greater numbers. So deciding to make 2013 into 14 by an update was a pretty obvious move. Didn't want to have 2 identical games, so one was made paid upfront and IAP less as many seem to want more games like that. I couldn't just pull the original '14 release as that would mean no updates for people with it. Just trying my best to give people options.
