I disagree with a lot of this "the majority of games are shitty now-a-days" argument. I think the feelings that gamers are having are due to the paradox of choice.
I think it's interesting to note that the average teenage gamer doesn't give two shits about 90s gaming, even after they've tried the golden titles. You might think that's very predictable, but I posit that it shouldn't be so. That same average teenage gamer will almost always readily agree that movies of the previous decade and the one before that were of higher caliber than the majority of what Hollywood produces now, but the same can't be said for games in their opinion. Obviously I'm generalizing and if anyone disagrees with me, they are entitled to their opinion and I won't try very hard to change it, this is all very subjective.
In the end, I suggest we all take our rose colored glasses off. I truly believe nostalgia clouds a lot of people's minds when it comes to topics like this. Let me give you an example. I just started playing The Witcher 2 (I haven't dipped my feet into the first). I immediately found it annoying to play for a single reason, when you slay an enemy, you aren't given the option to loot their weapon, armor, whatever else. I thought The Witcher 2 would be a re-imaging of this game I used to love called "Darkstone", basically a Diablo (2) clone, where it was all hack and slash and loot for cash. I popped in Darkstone to cure my sudden itch to play it, and I realized something after an hour...I hated the looting system. I always had to choose to leave things behind or I'd find myself sitting there with my inventory open for long periods of time trying to figure out which item I'd want to keep. I never realized how annoying "that" was, but back then, I had nothing else to play, I paid for that game as a teen with my own money, so I learned to like it.
I think gamers of the 90s have just assumed that games would steadily be more and more fun as graphics and complexity increased. That's just setting yourself up for disappointment. As visual capabilities and complexity increases, there are just more and more aspects of the game fans can point out they don't like. Everyone's a critic.
What will games be able to do when the next big jump hits? Ray-tracing, smooth frame rates, six different kinds of sampling eliminating jagged lines and blurry textures, stable online infrastructure, motion controls and voice commands.
But you won't like it. Because you will expect it to be 'more fun' than booting up your machine to run your floppy of Doom95. It won't be.
