Don't understand the obsession, as I'm very open to whatever comes down the pipeline to tell the truth.
If I hate, I don't buy it. And if I want it really bad, I'll try to make it, within the realms of possibility.
Really these publishing companies are essentially becoming Hollywood.
Solely my observations here, so feel free to take with a grain of salt.
[INDUSTRIES UNITED: Film & Gaming] Dive off into the world of film, and most critics will tell you that classics will always be more innovative and superior to the majority of that's produced nowadays.
The exact same goes for the world of gaming, where we are now presently is akin to the world of film in modern day, which is selling and producing franchises.
Both industries have become a realm of risk investment agencies, where they trade and dump cash into whatever is presumed to earn them the most profit.
(SideNote: EA, Ubisoft, Blizzard, among others are icons for publicly traded companies)
With new products gaining momentum within their own little world, they'll attempt to restylize and copy it.
For example: ESV-Skyrim. Almost every publishing company in the gaming business is looking to release the next open world RPG.
It's like our comic book phenomenon. Not only do we now have the technology with the capability to do so,
but with the amazing sales release, everyone agrees that open-world and sandbox gaming is where the risk is worth the investment.
[REASON OF ABSENCE: Facts of the Market] For many, there's recognition of a low dosage in quality and quantity for the Turn-Based genre of RPG gaming.
Final Fantasy has gone Anime-crazy (another industry solely lacking today) and is now throwing its chips into Action gaming,
while other valued franchises like Chrono Trigger have been remaining absent for years now.
One example of Turn-Based gaming not dying however, but just remaining out of the spotlight, is Pokemon.
A franchise built around and chokes itself with Turn-based gaming that is still celebrated to this day in some extent.
This has to do more so with Nintendo and their shining example of reluctance in altering their franchises out of risk investment.
They've gained a reputation for these games (Mario, Smash Bros, etc) that now they want to milk the cow until its utters give out.
The reason for the absence and diminishing existence of Turn-based rpgs in the corporate world is because of the risk investment.
With Final Fantasy (Turn-Based gaming's most cherished icon) losing money due to their stupendous amount of stupidness in gambling on low quality MMORPGs betting their reputation will uphold its profit margin (competing with Blizzard's WOW), and pooling ridiculous dollars into a failed FF13 package hoping it would be the next FF7 with fanservice, I think its safe to say that the market reflects itself.
That until a quality Turn-Based Rpg arrives to revamp the scene, no one is going to want to risk their investments on making the next TB-RPG.
[HONEST CONCLUSION: A Marketing Philosophy] As for your point about this:
us indies have the opportunity to turn junk to gold with new innovative ways to mix turn-based combat with engaging game-play or something fresh. People are getting bored with button-smash, God of War cut scene, "same old schema game-play" and Corporate always follow the Indies, we are the pioneers that get less pay and code in our bedrooms at 3 AM but we do it out of love and respect for video-games.
It's the same for the movie industry.
Indies try to come up with something innovative, fun, and fresh while Big Business attempt to thrive on the success of their ventures.
That philosophy goes for lots of starups/private vs Big-Business/public companies.
The lack of realization is that Gaming has now gained enough attraction to begin competing on the entertainment market amongst Hollywood companies and etc.
Microsoft recognizes this, and it's the sole purposes for their "Watching TV on your TV" feature for the new XBox, along with Netflix for the PS4 and PS3.
Most nostalgia for 90's gaming seems to glance over the fact that these companies were small and doing all kinds of risk investments to remain in the market, much like the 50's-70's era for film.
Just my two cents on the matter.
So if you feel there's a lack of Turn-Based RPGs being produced,
it's up to you to make them or wait for the next person to create them.
The way that I see it.
