Not enough attention was given to the "catch them all" concept, too much time was wasted on elaborate narratives that the average fat retard american child could not understand. And as the other anon said, they made the terrible mistake of making digimon talk, the american just couldn't keep up with what was said, nor remember who they were.
Worse, all their media was overemphasising early internet 2000's stuff, never going beyond that, they literally memed themselves into a nostalgic niche. GF/TPC was smart, bet on an intemporal scenario with revolving regions, and only used kanto as an heuristic to improve sales among the retarded american children, who are older now.
