Heh, i started working on a translation as soon as Koozek PM'd me, but it looks like many others chimed in meanwhile lol
Still, went through all the FB posts, take a look
She hasn't changed at all, i only had to change the spear because it lacked scenic impact [...] I drew a quick draft of Biggs and Wedge, but my prototypes weren't taken into consideration and ended up being two "mannequins" in a suit. She initally was supposed to always be accompanied by those two. Her origial was that of a member of a squadron that had specific attack patterns based on jumps.
Compared to my original concept, they changed Gentiana's clothes for script reasons. Still, the new dress kept much from the two versions i drew (a formal outfit and a party dress). The face remained unchanged. She also originally had red-framed glasses. [...] She originally had a white armour on the arm and a heavy sword at her side. Gentiana's original role was that of Stella's messenger, and a contact point between the countries of Tenebrae and Niflheim.
I gave birth to Ardyn in December 2010, before Kingsglaive was even in the works. The game's version is closer to my concept.
There were characters that i liked more but got removed from the story: they were closer to ninjas and very similar to those who appear in Kingsglaive but more japanese. [...] This stays between us, but Umbra the dog was supposed to turn into one of those.
I wasn't part of the 2010 group from XIII that "would have scatched their bellies" (and then turned into the XV one), i came into May 2010. I know i was called in when a (female) designer resigned since she wasn't able to get any kind of approval from the art director. Then, from 2010 till the end of 2011 i worked on the designs i got assigned with, without any big issues. That's why, when the team got resized from 200 workers to around 20 in 2012 (right before the arrival of Tabata and the Type-0 team), i was still there and worked with the newcomers till 2013. Then i left because i followed mister Nomura.
I had no story planned for Gentiana, but i can confirm you that the writers changed the script i received in 2011.
[...] I stand behind what Sakaguchi said about big budget games developement: it's not worth it anymore. But they are also very disorganized. The staff -200 souls- had to work when the story still wasn't completely definied. In fact, this story kept changing every 3 months and the definitive delivery date for the game was for the end of 2014 (who would have thought it would have been pushed back to November 2016?).
I'm already working on other episodes but what i did for XV was a lot.
[...] Sadly there aren't many new characters in VII Remake, i just reinterpreted the ones that already existed. I don't have the freedom of choice i had with XV.
