The NBA Live 14 demo released on
November 19, which was the exact same day that the full game went on sale at stores.
NBA Live 14 also was not shown to the public prior to its release, apart from E3, where all they had available to play was the one person practice mode that was later patched into the game.
Meanwhile, multiple games of Madden NFL 15 have been streamed in full, and most of its modes have been demoed on Twitch. There is
plenty of footage out there for people to make an educated decision on whether or not they will like the game, which is pretty much the complete opposite of how NBA Live 14 was handled, prior to its release.
