Also, using an existing engine often means giving up the possibility of having unique features or capabilities. Having the only game with multidimensional quad-resolution bumpmap tensors (in realtime!) can be a major selling point. Of course, in most cases, you'll get a better overall game by focusing on the art, story, gameplay, etc., but that doesn't always translate to sales.
With that said, a lot of great (albeit typically somewhat simple) games are made with frameworks. When I when to a few game jams back in college, we typically started with something so that we could have a "complete" game by the end.
