Well I would argue that you get enough information from him via the opening cutscene where he saves a girl from being raped and is blackballed out into a new school and town. Additionally the "blank slate" is a benefit because with the RPG choices you can use the opening cutscene to as a starting point for how you wanna RP him.Its kinda weird seeing someone have that reaction to another atlus game cause that's exactly how I felt with P5, the main character is a blank slate with no story to speak of and the main story is disconnect from what you do playing it.
The main character in Metaphor is not a blank slate. Which I dont know why they let you name him because it's totally pointless. But regardless he isn't a blank slate, he is voice acted, has his own personality, and even a backstory....probably eventually. There in lies the issue in that they've clearly got a whole story for him but I'm like 20 hours in now and I don't know shit about him other than vague little things.
It's so exceptionally poorly told that I feel like I'm taking crazy pills seeing people praise this game. Much the same way people praised FF16 when that story is fucking garbage! Yet people are out here simping for characters that suuuuuuuuuuck. I dont get it, I don't understand what the fuck is happening right now. Have we gone so long since something came out with a good story that anything half-way competent is something to go crazy for?
