I've heard all this stuff before. Especially the bit about not thinking its a good idea to shut up.
You're not the first person to think they could save a game by making a bunch of noise about it. Lots of folks did that. Head on over to mmorpg.com, or vault network, Even the defunct Crossroads Network, which I think went went belly up in 2000, was bought out by warcry, and then went belly up again in 2004(dates may be wrong) had people with a similar mindset.
This mindset has been around (and by this mindset I mean the mindset of if you scream loudly enough on the internet someone will hear you yell) has been around since probably before 1995, though it was really made popular in the days of battle.net with Diablo I, and Ultima Online.
Everyone was an expert.
And everyone was drowning each other out.
And nobody listened, because it was all talk.
You have a good idea? Approach someone you think might actually listen who can do something. Sell them on your idea. Make them believe you are there to help by putting something of yours on the line, not asking them to foot the entire burden just to try your new experiment.
You may actually get somewhere with that approach. At the very least you will learn that there are people in the products you enjoy who enjoy them too, and want to make them better for everyone. You may get a small glimpse into what it is like to be them, to work hard at something you really think is a good idea only to have the community turn their noses up at it for no other reason than it isnt what they asked for, to the letter. Try watching one of your ideas you put lots of work, money, and time into be torn to ribbons by the 'fans who love the game' and you may actually realize that they dont love the game at all. They love the ideas they personally have about the game, and nothing more. It's all about them.
This isn't fictional. This is real.
I speak from experience here. I speak from experience within EU here. Ask around. I'm sure you'll find out what I am talking about easily enough.
Talk is cheap. It's actions that count.
