What IS a "PQ"?

Here's a list of legitimate party quests in JMS

Henesys Party Quest
Kerning Party Quest
Ariant Colosseum
Monster Carnival (Season 2)
Ludibrium Party Quest
Elin Forest Party Quest
Orbis Party Quest
Ludibrium Maze Party Quest
Ghost Ship Party Quest
Davy Jones Party Quest
Magatia (Romeo and Juliet) Party Quest
Crimsonwood Keep Party Quest
Dragon Rider Party Quest

I'm sure some of these don't exist in GMS and PQs like Amoria doesn't exist in JMS, but you get the picture. Anything not in this list is not considered a party quest in JMS.

In short a party quest is deserted/abandoned minigames a quest requiring multiple players in a party. "Expedition" party quests are excluded because the primary purpose is to defeat a boss and is not a quest (Horntail has quests but you don't call is a Horntail party quest). Guild quest is technically a party quest but since it requires a guild, it's not considered a PQ.　4th job skills that req multiple people is also not considered PQs because they're not repeatable.
