Story paths

[Oddsboy]

I've played a chunk of the game (a while ago) so I'm still somewhat unfamilliar with the ins and outs. What are the major story paths or styles in this game? Is there a recognized name for these story paths. From my experience, it seems like most of them are faction related; you could be pro pirate, you could be pro huana, you could be pro Valian, you could be pro Rauatai. Are there any broadly recognized paths or are there so many variances that folks generally only worry about the specific choices in the plot (when x event happens you can chose to either help this person or kill that person).

Thanks!
