Seriously, this is the problem. Fucking moe bullshit. Any medium or genre that wants to be taken seriously by people over the age of 8 can't have this childish shit in it. Also the names need to be... well, not terrible. "Hyperdimension Neptunia." What? Why?
Hyperdimension Neptunia isn't even a good game. The problem you guys are having is that you're looking at all of these garbage RPGs being released and going "Wah! What happened to Final Fantasy VII-IX?!"
I think the biggest problem is that the games that had a good chance at doing decently well in the West were on the wrong platforms. Dragon Quest IX incorporated elements from "WRPGs", Kingdom Hearts: Birth By Sleep was basically a mainline KH game and what KH fans were waiting for since KH2, and Xenoblade also incorporated a lot of what people like about "WRPGs" and even had an explorable world. The problem was that DQ9 and KHBBS were both on the DS and PSP respectively late into their lives when people in the west stopped caring about those platforms outside of niche releases. Had they been on the 360/PS3 (heck, BBS probably could have done well on the Wii) they would have sold decently. Same for Xenoblade, but it was released as a GameStop-exclusive Wii title near the end of the Wii's life (and even then Nintendo didn't meet the demand for the game, as seen by its high prices).
Other than that every other title would have been stuck with niche status. And even DQ9 I'm not sure about.
