Organization: Harmonix

Record Run has the makings of a mobile best-seller: a short-burst, pick-up-and-play runner that lets players dodge obstacles to the beat of their own tunes.  With a triple-A pedigree from publisher Harmonix, known for catchy music game must-haves like Rock Band and Dance Central, the sky was the limit for this bite-sized behemoth.  Unfortunately, forgettable gameplay and a limiting IAP structure weigh down the experience and prevent it from soaring.The main gimmick behind Record Run is a popular staple of the rhythm genre: you can load any song into the game and it will generate a level synched to that tune.  Like Audiosurf and Beat Hazard before it, Record Run has chosen this method of content generation as its banner, and has barely supplemented its user-provided music library with four built-in songs. The problem is that Record Run also limits its user-injected library by forcing players to purchase "song slots" for every new song they wish to play, and offers no option to delete previously uploaded songs so a slot can be reused.  You'd better be sure you want a song in your library before you upload it, because it's not going anywhere.
