Here's where I'm coming from: I have experienced that after sharing what I'd like to see happen with D&D, about 90% of the responders are 100% negative and sarcastic (insulting). Someone will go through and respond to nearly everything I suggested, with droll critiques about how each one is impossible. Only a few say something positive or constructive.
In any mode of communication, there's an element of self-awareness for the communicator wherein he or she attempts (or not, as they choose) to view how a given piece of communication will be received based on the presentation. If people are being critical / snarky, a portion of that response is most certainly related to the presentation of the original post.
Seventeen books? Detailed in overbearing, profligate fashion, in a tone that can best be described as self-flagellatory?
If you wanted serious, reasoned responses it might have been better to narrow down the scope of your ideas to a more succinct core.
Simply spouting off a laundry list of "I want this!" comes across, frankly, as immature ranting.
What was the purpose of your original post? To spark ideas? To discuss the future of the D&D game? Lengthy postings with a distinct lack of self-awareness aren't going to generally lead to the kind of exploratory conversation you were obviously expecting.
I have to agree with everyone who has stated up to this point that in spite of our love and ardor for RPGs,
it's a business. Investments into product have to have a foreseeable return in sales, or it's worse than wasteful, it's destructive to the producer.
And frankly, no RPG product currently in existence, nor anything that could be produced in the next 10 years is going to produce another Golden Age. You know what a Golden Age of RPG play would look like to me? When the idea of playing a tabletop roleplaying game is generally seen as a social activity no more odd, weird, geeky, nerdy, or otherwise out of the ordinary as getting together to hold a fantasy football draft. When in casual conversation at work you can bring up the topic, and have 90% of the population look at you and completely understand what you're referring to when you talk about "character generation" and "level 5 wizard." When the act of self-selecting oneself as a member of the RPG community doesn't generally require hiding that self-selection from coworkers, and people you meet for the first time. When those of us as members of the RPG community can exercise the necessary awareness and self-restraint from brain-vomiting everything we think is "cool" or "awesome" about our hobby to outsiders, which is more likely to turn them off than pique their interest.
Frankly, self-indulgence along the lines espoused in the OP is an active detriment to reaching RPG social acceptance, not a benefit.
