I'll make a crosspost, as this was originally made in part to combat the thought train of Megamix ruining originality: I have one big stance on this: "Originality is the art of concealing your sources." - Benjamin Franklin. As an artform progresses, there will be no such thing as "originality", only taking an existing idea and doing something new with it. Expecting true originality in an artform which has been around for over 15 years is a fool's errand. It isn't Megamix's fault, nor is it any certain hack's fault. It's the fault of simply the progression of an artform. Look all around you and you'll notice this same thing applies to EVERYTHING. Art? Recycling ideas from previous artists. Music? Same thing. Video games? Same thing.
