Its a philosophical stand in game design.
- If the game has strongly defined protagonists and your role as a player is to accompany him/her on their journey, then a 3rd person perspective is the preferred choice.
- If the game doesn't have/need a strongly defined main character and wants to create the illusion that the player is the main character, a 1st person perspective is the preferred choice.
- If the game doesn't have/need a strongly defined main character and wants to create the illusion that the character commands the characters in the game, an isometric/bird's eye perspective is the best choice.
The problem is that, sometimes, even experienced game designers forget about that distinction, or adds them to make it look good, which leaves some dissonant scenes, like Skyrim 3rd person or God of War last boss...
