- Though not in the same style as the other games of the series, it would seem as if Hillsfar is indeed part of the plot tying together Pool of Radiance and Curse of the Azure Bonds. The manual for the latter game states that the party ventures to Phlan (Pool of Radiance), then Hillsfar (Hillsfar), and then to Tilverton (Curse of the Azure Bonds): "Like most heroes, however, the adventurers who freed Phlan did not stay around. It is known that they took a boat from Phlan to the City of Hillsfar across the Moonsea. From there it is rumored that they traveled south and west in search of further adventure." Thus, for lore-based reasons, Hillsfar is grouped within this series.
- This game, which came a decade later, is not connected to the previous games by being a typical sequel, and uses a much newer engine. It is connected to the first game in terms of location, setting, and name. It is also licensed to be part of this series. For this reason, Pool of Radiance: Ruins of Myth Drannor is included as part of the series.
- This Game Boy Advance game is not a direct port of the original game. Only some features are very similar, such as the story. However, the combat system is much more like the older Pool of Radiance game, instead of first-person dungeon combat. Due to licensing and the name, it is thus classed as part of this series.
- This game was the first graphical MMO to ever be released. It is very similar in style to games of the Savage Frontier series, though it is not connected in plot. It is also not connected to the plot in the Neverwinter Nights series, however, it shares the name. Due to this, and potential licensing reasons, it is classed as part of this series.
