personally, i think sqare's doing the best they can.

they know the draw of ff7, and they would like to continue the story/make more money off of it, right? however, they don't want to make it stagnant by just remaking the game. they're continuing the ff7 storyline/universe by taking different routes/genres to do so.

think about it. there's a movie, a new shooter type game, the cell phone game.... that's three new genres that the regular ff7 fan might not frequent that much, but they're going to broaden the reach of the ff7 mythos by going new routes.
