One can form an opinion about it, but it is a personal opinion, and not much more than that. It is very clear that people *aren't* very good at predicting the popularity or success of things in an moderately open marketplace. If we were good at it, we'd more often then not pick the right stocks to invest in, always know what will be the next Cabbage Patch doll or Beanie Baby. But, we don't.
Thus, your posit here is just incorrect.
And that's setting aside how "success" and "long lasting" are not well defined.
Personal opinion is what this thread is about. Nobody is looking for a scientific analysis as to how long the game will last, so my post is spot on.
