It's less about otakus as it were, and more about companies pandering to the lowest common denominator. Among these are the various adherences to story and character cliches that they think are popular with their target audience and belief in what sells in the short term rather than looking at long term sustainability.
As an example, let's take Final Fantasy VI. The first half of the game was a focused and linear trek through a well-paced and coherent story. The second half consisted of non-linear forays into more personal stories and hidden characters, dungeons, and abilities. The story was well told and had a lot of subtlety for a video game, despite diving into melodrama every so often. Consider: players who took the time could discover hidden facts about the characters, such as Shadow being Relm's father or Sabin and Edgar's situation being placed on a coin toss. But this was all they could do. Shadow will never reunite with his daughter and Sabin never truly returns to Figaro. It givesthe players who explore the game information and allows them to draw their own conclusions from the situations. Is Edgar's place as king something he desired or are his charm, competence, and ability merely an obligation he had to uphold in honor of his father? The ending is also suitably melancholy, though hopeful. Sure you saved the world, but it's still destroyed, though life perseveres.
Contrast with Final Fantasy XIII, all the information is handed to the player on a silver platter. There is no subtlety, no grace in the presentation, only mouthpieces for the developers explaining the plot twists ("YOU WERE MISTAKEN ABOUT SERAHS FOCUS" "OMG IVE LOST THE WILL TO FIGHT"). There are no secret characters, no hidden sidequests or cutscenes to flesh out the crappy ass cardboard cutouts they call characters, no hidden dungeons or items, and the ending, as well as the cutscene before it where everyone screams OUR FOCUS IS TO MAKE THE IMPOSSIBLE POSSIBLE is some of the most embarrassing shit I've ever had the misfortune of hearing come out of my speakers.
It seems that JRPG developers think we get stupider with age or the pubescent crowd that Final Fantasy (and other JRPGs) panders to are stupider and less capable of cognitive function than the last one. I've been playing FF6 and aFF13 concurrently oh my GBa and PS3, and I'm consistently having fun with the former, whereas I have to drag my feet to get through even just one chapter. When Matsuno left Square, he took the last vestiges of dignity the company had with him. The company is now a bunch of morons who push out stupid crap to appease mouthbreathers who don't want to think or be engaged when playing games. I almost hate myself for saying this because honestly, I hate these new vs old arguments. But with the JRPG, I can only say that it's now even more of a bunch of bureaucratic bullshit than many western companies. Don't believe me? Look at FF12. Executive keddling took what could have been an instant classic and fucked it up beyond reason. Or hell, look at FF13-2. They couldn't make Lightning a deep or likable character, so they turned her into a Soul Calibu fanservice reject.
