Lol, you could honestly take her out of the game and nothing would've changed. That's how bad her character was, the whole sacrificing your livelihood for a man or person is so outdated and repulsive. Noctis had more chemistry with his bros anyway.
The whole arranged marriage angle in that game is really repulsive tbh. You didn’t need that to be the (pretty flimsy) reason for the road trip. It’s one of the few things I genuinely don’t like about the game — it really sticks out like a sore thumb given the whole “modern(ish) royalty in a fantasy setting” vibe Noct gives off. I will say she’s a little more interesting in that novel that came out last year, but like… by then it was way too late for her character. I feel like XV didn’t necessarily even have to have a canon romance, and I especially don’t think it needed to be that one lmao — the game’s ultimately about the main four and their time together. Everything else feels forced.
Ultimately, it honestly felt like they were going for some sort of Aerith-scale sacrifice/death without like.. any real understanding of why Aerith’s death hit so fucking unbelievably hard and was so important to the plot. Hell, even if you just contrast Noct and Luna’s sacrifices, only one of them is actually really memorable and upsetting because Noct is the character you actually get to know.
But yeah. You know it’s bad when I’ve been asked who “the blonde that seems like Noctis’ love interest in ffxv” is by someone who hasn’t played the game yet, and my response is just automatically, going down the line “You mean Prompto?/Oh so you mean Ignis then??/…did Gladio go through a blonde phase I don’t know about???” Lol.
