I thought once Apple implemented videos in the App Store everyone would have been all over this feature. Why aren't most devs using this? I still see many new releases without a video. Don't devs know that it's hard to sell a game by static images. Especially since many games look horrible by going by only screen shots.
I don't know, but I can guarantee you Flappy Bird wouldn't have been as popular if people would watch a bird going trough tubes for 60 seconds.
