Have you even played Persona 4? Your comment of the dating sim thing kinda shows me that you probably haven't. If you had, you would know how utterly stupid that comment is. Not to mention being very wrong and inaccurate. And saying the writing is bad? I wonder even more if you have really played it. But hey if you have and you think the writing is bad, I would really love to know what RPGS you think have good writing.
I'm on my second playthrough of it right now, don't get all fired up and mad because of my opinion you fanboy. Compared to the previous Persona's, P4 reminds me more of a dating sim type game. I don't know the exact term for those games based around dialogue trees and relationships with other characters, so I'm just gonna go with dating sim-esque. At least half of P4 is spent eating lunch with Yosuke or helping Yumi with her daddy issues, and its not just a side quest like romance was in ME2 for example, it's a key aspect of the entire game and you can't really play the game and do well if you don't study and pass your midterms and then go out shopping for groceries with Yukiko.
The writing, especially the dialogue is atrocious. The characters are extremely thick and are pretty much clueless to the most bluntly obvious things. Yosuke seems to be the only one that knows anything but even then he's not too sure of the most obvious statements and has to ask the PC if "X shadowy figure in the TV that looks almost exactly like X character is in fact X character). Most of the dialogue is extremely vapid and insipid, it makes me wonder who thought some of those lines were necessary at all. And I swear Tommy Wiseau must have been in charge of the setting design, there is all kinds of wrong with it. From your entire party sticking out from the class like soar thumbs to Nanako making breakfast when there was already breakfast on the table.
Not to mention how extremely repetitive the plot is. Stuck in TV? Rescue them. Stuck in TV? Rescue them. Stuck in TV? Rescue them. Repeat
Oh and the big reveal on the girl that set the entire plot into mention was that she is just some pointless character that contributed almost nothing to the plot after her initial appearance? Christ it'd be like The Dark Knight except at the very end the Joker comes out and says it was the Bank Manager planning all of it.
The only thing interesting about the writing is the premise, oh wait its just a carbon copy of JoJo's Bizarre Adventure Part 4: Diamond is Unbreakable's premise. Then again the whole Persona franchise is loaded with JoJo references.
RPG's that I think have good writing? Off the top of my head: Final Fantasy IV, Fire Emblem IV, Legend of Dragoon, Wild Arms 3, Final Fantasy Tactics, Grandia II, Final Fantasy XII, Mass Effect, Baldur's Gate, Nier Gestalt, Tales of the Abyss, Shining Force, and Golden Sun (well I wouldn't say the last three were as good as the others but they were above average). And Majora's Mask if you count that, and Fallout New Vegas, although I never actually played that one myself just watched a friend play through it.
There are only two reasons someone would say something so utterly and flabbergastingly (yes, I know that's not a real word, it's the only way I can convey my feelings on this) incorrect.
1) Troll detected!
2) You've never actually played P4 and are basing your opinions on that parody comic.
Please read the above post.
Also the hiimdaisy MGS comics are the only funny ones, the P4 ones are only funny when watched as that fandub by Antfish.
