I really seem to have a filter how I see thy this that I just found confirmation about the original disappointment of when I was a impressionable young chess fan, in my comment above,
but I can only say that I really would have felt very hurt by this limitation if I could transplant my childhood me to today. I have such a distinctive memory of the way I felt about arbitrarily elitist and opaque barriers to intellectual pursuit.
I'm not doing a very good job expressing myself probably because I have such a clear recollection of the way I was as a kid, but I think that my earlier comment about how better PR and marketing would be a help with Kasparov's image when you consider this limitation remains opaque in functional reality even if the reason of the limit is clear any inquiring mind has to ask why not take it more slowly / soft launch, as you suggested, or if something else isn't quite there yet.
But as it stands, I can only pre-register. For a chance to be one of 6400 players granted early access.
