When this tradition of Obsidian to give weird names to basic fantasy 101 tropes will stop? It is just plain pedantism. Okay, we made the PC LARPER pirates faction... hmm... lets call them Principí! Originality, right there!
How dare they have vailian pirates use a vailian name for their organization. The nerve!!
So? What is the difference between a vailain pirate and a run of the mill Pirates of the Caribbean one then? Oh, yes, they worship the gods of the sea and wind and are... against be merciless... whatever this means. Some fantasy RPGs are more honest, they don't care into fleshing out their run of the mill pirates and just name them pirates or corsairs. However, giving pompous names to things is a really superficial way to pretend any difference from standard fantasy.
My issue isn't with the name exactly but the lack of depth on PoE factions, the name is just insult to the injury. Factions on PoE were mostly abstracted concepts made of fantasy tropes that never truly came to life, same problem with Tyranny with its Earthshakers and pompous names to all kinds of banal shit. Okay, let's get this concept here, lets get that trope there and mix all together with an weird name and BOOM, new fantasy that is totally different from standard fantasy drivel that I've seen 100 times. If on the game, on the actual quests and not on some throw away lore, they really don't give a strong reason why the writer bothered into giving an special name to their generic pirates, it will be the whole Fampyr thing again.
If Obsidian just wants to make generic fantasy, I'm fine with it, I like Forgotten Realms and that is high fantasy as it can get but this "We are making pirate dudes that raid shit... no... Príncipi." makes me laugh like no tomorrow as it doesn't add absolutely nothing to the game beyond hipsterism. Of course, they could be making interesting stuff up for this faction but after how PoE and Tyranny turned out on this regard, I'm pure cynical skepticism until proven otherwise.
