Yes, but "point of view" doesn't necessarily mean "main character", that is essentially telling us who the narrator is. It's possible to have a first-person story where the pov narrator is not the main character, they are basically telling someone else's story, but from their viewpoint. The Shawshank Redemption is a good example of this, where Red is the narrator, but the main character/protagonist, is Andy. It's Red telling Andy's story, so the comparative title there could be "My Prison Friend" - where it's the "friend" who is the main character, not the "My".
To be clear, I'm not suggesting that Christian is the MC here, I'm just pointing out the broken logic of using the game title alone to confirm Vivian as MC.
