That's the gist of it, yes.Well, the only that is listed there is some idea (possibly conjectural) that never made it onscreen. What did make it onscreen, however, was that baseball largely declined due to people "not having time for it" anymore. If anything, it kind of implies that baseball wasn't competitive enough to keep people interested in it...Oh, really? Care to explain THIS, then? (hint: look under "Background")
In If Wishes Were Horses didn't the Buck Bokai character say that people actually wanted faster games with more action and less subtlety. I am paraphrasing from bad memory, but I thought that was the suggested reason behind it.
