first of all, nice post. i liked it and i like you already
i think that there has been a huge influx of really crappy games, particularly on the Wii and DS (people don't hate on me, im not flaming - i have both and i like them). i worry that there are so many games being churned out willy-nilly to sell a fast buck, that "gaming" aint what is used to be.
but no worries, because fantastic games are still being made AS WELL. as long as you can still go pick up a good or even great game, you can just ignore the rest of them. there's just a much bigger market than there used to be, its a lot less of an exclusive club of "geeks and losers", and most people will end up playing games at some point, if not be at least familiar with the console names.
i think its a mixed bag, really. i do agree with what you're saying, but i dont think we need to worry just yet
