The problem is that gamers can't really resolve the problem. This was exactly why people hated casuals and games going mainstream, and what we saw coming. The average person playing games doesn't visit sites like this, pay attention to what the companies are doing, or really care... they just want their shiny product, and line up like bleating sheep to get it, and the mainstream market does this with everything. What we're seeing is games being marketed pretty much like any other product directed at the masses out there.
To be fair, a lot of sites and "gamer personalities" did contribute by saying "Casuals" aren't an issue, and how we should welcome the mainstream, and how all the money they brought in would wind up making games better. That never happened, and instead it saw games being dumbed down, but then the gaming media said "well this isn't a problem, because they still make other kinds of games, let the casuals have theirs", and of course this lead to the state we're at now where almost everything has become what amounts to a short, glittery, casual game even if pretensions are made of it being something else. We've gotten to the point where we tend to look for the exceptions to this general rule among the piles of over promoted, steaming, crap. You can almost feel the irony when certain people and sites who were once championing casuals and the changes to the industry, are now some of the most vocal critics, sadly now that it's too late.
At one point gamers probably could have stopped this, especially if the media that supported us went far more elitist, and we were actually more aggressive (as opposed to demonizing the aggressive and elitist), but right now even if pretty much every serious gamer and personality from sites like "The Escapist", "Destructoid", and others were to achieve some kind of unity, we'd still lose, because for every one of us, there are 100 sheep. For every personality we can bring to the forefront from the gaming community, a company can basically create three from professionally trained actors, ad campaigns, and officially sponsored sites if they choose to. Short of some kind of violent revolt, where say we all arm ourselves, become a terrorist organization equivalent to Al-Quaida, start murdering people in the game industry (say having Jim Sterling decapitate some secretary who works for EA on his show to frighten the general employee and show the authorities can't protect them), we aren't going to do crap at this point... and really we're pretty sane so it's not like we're going to kill anyone or engage in massive terrorism over bloody video games. All jokes and rants aside, as much as I love turn based RPGs, and as POed as some people are that they don't make "real" Sonic games anymore, or whatever else, nobody is actually going to engage in armed insurrection about this kind of thing... even against EA or Team Sonic.
In short, I personally continue to fight, and admit there are a few tiny glimmers of hope once in a while, but I'm not very optimistic. We're pretty much at the point people have been saying for many years now we were going to reach if trends continue, but nobody wanted to accept. "Real gamers" are a big market, but even voting with our wallets we're not the biggest market and can be cut loose easily now. Sort of like how there is plenty of money to be made just within the subset of "serious RPG gamers" who want crunchy turn-based games, but not enough money compared to other markets, so again they can be easily ignored. The last real hope is that the casuals would turn their back on gaming as some passing fad, but that didn't happen, and right now saying that the industry can't bank on this kind of thing is equivalent to saying Television is a passing fad, and network executives are fools, with everything inevitably going back to Radio once people get tired of it... it's not happening.
