It's just an IGN list. Lets not get into semantics over what makes a fan or not
I would usually agree with this and I still do here, to some extent, but I think it's problematic to create list as though they are recognizing the series as a whole when that's clearly not the case. As a celebration of all the consistently great characters the Persona
series has gotten, this is pretty poor.
And, if I'm wrong and they actually
did fully consider the P1 and P2 characters, I would have wanted them to acknowledge how little they are represented in the list and explain why. The "Persona started at P3" meme is humorous, but it's rather disheartening to see just how true it seems to have become. My first was P3FES and then I went to P4, but I still visited the previous games later on and discovered how great the P2 cast was, making me like them more than P4's cast.
They could have just been earnest and put "Top 10 Persona 3 and 4 Characters" and it would have been cool.
