They sold that many because that many people wanted them, they deserve their sales because they appeal to enough people and were advertised well enough that people knew they were released.
If you want me to give my opinion on which games would be enjoyable for me if I bought them, then my list of games that wouldn't deserve it if I happened to be cloned 1 million times would be everything there minus High School Musical, Game Party, and Smarty Pants.

The same thing applies the other way around.... Okami on the PS2 did not deserve to be a 1 million seller, I mean sure some people though it was amazing and were very vocal about it, but clearly despite what must have been at least 1 million people hearing about it being amazing from online forums and yet they still didn't buy it.
