Persona 3
>Yukari
She just complains about her mom while door-kun nods for ten instalments. Breaking up by hugging her is pretty funny though. 1/5
>Fuka
Boring with a capital B. Literally nothing happens. Contender for worst social link in the series. 0/5
>Mitsuru
The drama with her fiancé is interesting, but her being surprised at hamburgers really makes me take her less seriously. 3/5
>Aegis
Pretty generic "teach a robot to have feelings" plotline. Most of her links are just heavy-handed ways to exposit the game's themes. 2/5
>Chihiro
Pretty good actually. Has a clear character arc and obstacles to overcome. Plus the MC helps her in tangible ways instead of just listening to her rant, like he does with the other girls. 5/5
>Yuko
Never did her link.

Persona 4
>Chie
There is a kernel of a good romance link. But too many of the hangouts are wasted doing Sweet FA. 2/5.
>Yukiko
Only slightly better than Fuuka's because being trapped in a small hometown is a better premise for a character. Otherwise... BORING. 1/5
>Rise
Good for the most part. But frankly, I didn't like that she went back to being an idol after all was said and done. 4/5
>Naoto
Garbage. I couldn't care less about her grandfather's stupid riddles. Plus, I feel like an ass for stealing Kanji's girl. 0/5
>Marie
I don't hate Marie like some people; I'm mostly ambivalent about her, including her social link. 2/5
>Ai
Easily the most interesting romance route in the series because there are real consequences to screwing up with her. One of the few Persona characters who acts like a real teenage girl and not an anime trope. 5/5
>Trombone girl and theatre girl
Didn't do them

P5 in next post.
