Puyo Puyo. The three best games in the series were Puyo Puyo 15th Anniversary, Puyo Puyo 20th Anniversary, and Puyo Puyo Chronicle (25th in all but name). None of these games ever got released outside of Japan, but after the crossover did well overseas there were high hopes in the community we’d get a similar mainline game for the series’ 30th anniversary.
I wrote a very long essay about how that didn’t happen, and the state of the series ever since. And a more recent followup video on Sega’s newest blunder.
