It's a matter of perspective,if you look at it closely.Melody is a different kind of storytelling and different plot,with different characters.You can like them both,or 1 more than the other,but you can't say that that one is a better game than this one without stating the facts that they are a lot different.
I like both Melody and DmD,but I also think that Melody is better than DmD,with Melody being feisty,smart,sometimes independent and a rebel,and D being a complete dumbass.The stories are simillar,but told in a different way,and that is one of the reason that makes it better,depending on your own perspective of life and the society you have grown up in and also keep living in.
Everybody is entitled to have their own favourites,despite their fetishes or preferences in games.You can't say that he is wrong just because his opinion is different than yours and a lot more like you.
Just my 2 cents.
