Player character, I've moved around far too much to be a background face. I sure do wish the player would stop switching up his gameplay style though...
Probably a player character. I have been nerfed a couple of times for being too OP and I lost a parent earlier than expected which adds to the tragic backstory common with player characters.
I'm a playable character. I know because I realize the ways I could've done something differently, whereas NPCs in a game have only one way to do something.
