Wow, fantastic article!
It has me a little worried about the future of gaming, though...the moment I stop being able to buy games like Demon's Souls is the moment that my passion for games starts to dry up.
Luckily for me, I'm still young and naive. I'm just as excited about some of Nintendo's latest and greatest as I ever was; Metroid: Other M looks superb, and Paper Mario 3DS has me all kinds of excited.
However, I think I get what you're saying. There's a lot less for me to get excited about this year than any year previous, even with all of the technological innovation. I've had the sinking feeling for a while, now, that videogames are moving in a direction that I'm not entirely on board with - I argued, vehemently, that New Super Mario Bros Wii is a flawless game, overlooking the fact that a 'superguide' had been added, and the background art, at times, looks even simpler than Super Mario World...I thought that was due to having 4 players possibly on-screen simultaneously, but I could be very wrong.
I love Nintendo's innovation, but I don't like how some of my favourite games are being made 'easier', like Megaman 10. What's the point of a platform game when all the holes are covered up!? The level design had me worried that, in making the game more accessible, Capcom lost out on a lot of chances to make their game even more interesting, missing out on using the weapons as effectively as they did in Megaman 9.
Anyways. I'm all for casual games, but keep them the hell away from my Megaman and Metroid!!! I've gotta say, to close, that indie games hold more sway over me than a lot of the biggest releases out there...I think that, even if the day comes when sub-genres are lost forever, innovative games will live on through indie game networks, like Steam, PSN, XBox Live, and, to some extent, Wiiware.
I'll always have my virtual console, at least.
