Persona 2: Eternal Punishment
Maya: Gonna give her a 9.5, because I think it's unfair to give her a score based only on EP!
Ulala: 7, could have been a lot more interesting as a foil to Maya.
Katsuya: 6, nerdy cop
Baofu: 8, interesting dude with glasses and a complex
Tatsuya: 0.5, boring
Nate: 7, they needed to do more with him
Ellen: 8, loses a point or two for TV SUMARU FUCK THAT DUNGEON CHRIST
Guido
Ishigami Chizuru: 3? She didn't really do much.
Tatsuzou (Tatsuya Suzuo): 3? Also didn't really do much.
Tatsudou (Tatsuya Sudou): 4 VOICES VOICES (but also didn't really do much)
Nyarlathotep: 8, +1 for the answering machine
Legaia 2
Lang - 4/10. Uninteresting character. His characterisation adds enough to prevent him from being boring, but no more than that.
Maya - 8/10. Adorable personified. She has the best characterization of the whole game. There's no character development though beyond "hey I got my voice back and will from now on behave as if I've always been able to speak!" and despite the game hyping her powers as being important, it doesn't feel that way.
Kazan - 6.5/10. I like that they made a teacher type who's experienced rather than wise. That turned out to be much more fun than expected, but like Maya he doesn't have anything apart from characterisation. If anything, his backstory with Rauss is a discredit.
Sharon - 7/10. Well, she is rather funny. Like the rest of the cast, she got nothing apart from characterisation. Her dream of becoming a pirate is not as bad as Kazan's backstory, but still rather silly.
Ayne - 3/10. Was there any point to him? Well, he does have a few amusing scenes, but for the most part he may as well not have been there.
Bubba - 5/10. Rather amusing, especially him being a bishop.
Elliot - 2/10. First the game tried to make me hate him. Then at the last second the game tried to make me feel sorry for him. The result was that I neither felt sorry for him, but didn't either feel any satisfaction for beating him either.
Marienne - 2/10. See Elliot.
Doplin - 3/10. Mostly an idiot. He was portrayed as a total scumbag, but I couldn't care less about him using Elliot and Marienne.
Velna - 5/10. Props for simple agreeing with the villains goal, but for her own reasons. Yet somehow she came of as non important despite being second in command and having an unique power.
Rauss - 3/10. Really silly backstory and no real character to speak of besides wanting to test his mettle against a worthy opponent. His insanity effect was cool though.
Avalon - 1/10. Stupid backstory and inefficient as a villain. He came of as a credible threat at first, but then he decided to just allow the heroes to run free. Either you try to get rid of them or you try to use them, but don't just sit there and do nothing. Instead of him being an active threat, he was just given a stupidly amount of power that required complete nonsense to counteract.
buuuurp copying Neph/Crystalgate, tweaked a few numbers here and there but.
