It's not nostalgia.
bazilisek: No, that's wrong interpretation of the data. Or more precisely, ignoring their heavy bias. Contemporary movies never make it into these lists because they just do not have enough votes from a diverse enough population. They haven't been around long enough, and the reactions to them tend to be very polarising and extreme. The IMDB list doesn't just list the movies with the best score, the number of votes and their distribution has weight there as well. It's a deeply flawed methodology, really.
To rephrase: The Shawshank Redemption has been the number one film on that list for ages. Go ahead and find me someone who's going to name it the best film ever made. It's not a movie that would be universally loved, it's a movie that's pretty much impossible to hate. There's a difference. And it took a crazy amount of exposure on TV to shoot that film on top of that list.
Frankly, the argument that [insert aspect of culture] is getting much worse than it used to be is utter bullshit, as can be proven by the very simple fact that it has been applied to every period ever. Hell, I'm willing to bet it was first used for cave paintings.
I have to +1 you. I'd plus you more if I could. The IMDB list could possibly be skewed by the exact type of nostalgia that skews peoples' perceptions in the first place. If we're told, (just as an example, this doesn't apply to everyone) that Casablanca is a "good" film, we'll be more amenable to think so. I like the movie personally, it's just an example.
It's psychological to a large extent. Like others have noted, we filter out the bad stuff in the past. It's natural and very common. There are bad trends in gaming for sure. Also, it's not as if we haven't changed--games and gaming have changed.
This entire concept goes beyond games and encapsulates almost the entire human experience.
I also am a grumpy gamer, by the way. I also don't typically play all the newest games out there. But when I try to be objective, it's important to not categorize everything by the year it came out.
