If you count up every game rated "good" or better that has another game in the series rated "good" or better, you end up with 377 games from 112 series.

If you just look at those as part of a big series (With 2 or more other games rated "good" or better" it's at 295 games from 70ish series.

So there's about 250-300 games "good" or better that were stand alone games or with [censored] sequels. A couple of more games are in series that cross platforms. Some others are debatable (ie, Bully, Arena Football). I'm going to attempt to make a final list of all ps2 games that fit a certain criteria of stand-alone games.
