Games today are much like games 10-20 years ago… some are good, some are bad, some are just bland. Sometimes you buy bland games because you love the genre and you love to consume.
Despite loving the classics I don't agree we suffer a dearth of quality today. The experiences are certainly different, but the quality level isn't really. Remember that when looking back to the 90's and such we focus on the classics, not the crappy games no one cares to remember. 20 years from now I will look back on Fallout: New Vegas, Risen, Mass Effect 2 and others with fond memories and likely forget all the crap that comes out today. People in 2030 will be talking about how much better games in 2010 were as well I would assume.
I don't think there's any way to measure quality on an objective scale - as we've already been through.
My point is, basically, that my experience with modern games is - generally - VERY different than my experience is with classic games. Modern games just don't measure up. There are exceptions, obviously.
Whether that's about me or the games, or whatever combination, is almost impossible to say.
All I know is that the vast majority of games today can't measure up to the quality of the past.
But, one should keep in mind that the quality of the past isn't some kind of infinite spring of perfection. We often had to wait months and months between the quality.
I think it should be said, though, that from ~1990 - 1996 - there was an abundance of games that represent the peak of game design, from my point of view.
A peak that hasn't really been approach since then. Games have been released that may be just as good, but rarely because of any improvement in game design. More improvements in production values and polish.
I guess what I'm saying is that I miss the times of innovation within my favorite genres. I'm not talking about Braid/Portal or games like that. I'm talking about RPGs, turn-based tactical, grand strategy, and others.
I have a hard time seeing ANY genuine improvement in game design. I've seen a zillion enhancements in visuals, interfaces, or "streamlining for the masses".
That doesn't mean there aren't any superb games being made.
Gothic can easily be argued to innovate over games like Ultima 7 - for instance, but I think that's more about the visual approach than the core design. In many ways, the core design is inferior. But it's different enough to represent evolution on some scale.
