If someone owns DQIII on an older console and doesn't care about graphics/music/having it on a new console/adding to sales numbers, is there any point in playing the remake?

I feel from what I know, there isn't a point. If someone already owns the game, is there any point? Is there something significant that was added that makes it worth it? I thought it would be a good gift for my friend, but they don't want it if there's nothing new for them.
