@morterlust: Thank you for the kind words about the localization. I wasn't involved in the quest and character writing for Scarlet Blade myself (I mainly worked on SB's mountain of UI/menu/system text and some incidental text, like the flavor text you see on enemy drop items), but I'll definitely pass your post on to the story team. I can't speak for them here, but I'd take comparison to the SNES greats as high praise.
One of the really interesting things about Scarlet Blade is that while in most games you play "as" a character, SB frames the player and the player character as different entities, which allows the game to have the character talk directly TO the player (which in any other case would be 4th Wall-breaking to the extreme). This required some dexterity in the writing of things like costume descriptions - we had to take into account that the commander, not the Arkana, is the one buying the costume, and phrase things in ways like, "You'll go weak in the knees when you see her rocking this sexy bustier!" instead of "You'll feel like a queen in this sexy bustier!" There were a number of tricky cases like that, but hopefully we pulled it off and correctly differentiated the things directed at Arkana from the things directed at Commanders (that is, you the player).
Now, about the "bipolarity" of the Arkana. What you're seeing there is, as previously mentioned, the midway-state between the direct translation (brought to us by our excellent and very speedy Korean translators) and our localization. In the original text, faithfully translated, the Arkana were very subservient and pandering to their commander, almost to a worshipful degree. The story team decided they wanted to take a different tack and made the relationship between the Commander and Arkana more rocky. When you go into Closed Beta, that tone should be much more consistent, because after Alpha we finally got LivePlex to put a month's worth of localization work into the game.
I'm really curious which type of Commander/Arkana relationship players would prefer. What I would have liked is if we were able to write each class individually, where a class like the Whipper would likely have a more antagonistic relationship with her Commander, but the Medic might actually be very lovey-dovey and the Defender might view her commander as a valued partner working toward the same goal. Seeing a player choose their Arkana based not on skills or stats but on personality would be really interesting, don't you think?
Right now, all Arkana use the same dialogue responses because responses aren't divided by class. We asked LivePlex about that, and while I don't know if they'll create subdivided responses for every class, we may at least get subdivided text that we can change based on whether your character is part of the Royal Guards or the Free Knights. I won't
promise anything there, but that's what we would
like to do, given the devs' cooperation and the time to do it (in between continuing to do things like new content updates).
I hope you're all looking forward to Closed Beta - it may help answer some of your lingering questions about the story and characters. Cheers~
