PookaMustard: Games don't age or reverse age. They play well today, they play well 20 years from now. They played well 20 years ago, they play well now. I don't believe in such a thing as 'games age'. Sure, Super Mario 64 can be a much better game than most of what we played now, I know that feeling. But its not because Super Mario 64 'reverse aged', more like the games we play today are just dropping frequently in quality. And if another game is surpassed by another more recent game, its because the more recent game just stepped up in quality over the older one.
These are my two cents. But yes, if you don't use the 'age' word, then I could say that Super Mario 64 is definitely better than most games I played today.
I can't be certain what the original poster meant by "reverse aged" but here is how I personally interpreted it before responding. Naturally as time unfolds everything ages, but what do the concepts "aged well" or "did not age well" really mean? That's subjective ultimately. For me it means that when I play an older game now, how does the overall experience of playing that game now compare to the overall experience of playing it when it first came out? For any given game it might feel the same as it did back then, or it might not be anywhere remotely exciting as it did back then, or it might be even more entertaining or exciting in some way now.
For me, "aged well" means "despite the fact it is old, it is still just as fun and entertaining or maybe moreso now than then because <reasons>". "Did not age well" means "it's not as exciting to me now as when it came out because <reasons>". In both cases making note that this is an individual and personal thing that is ultimately a subjective opinion and not a conclusive scientific fact that applies to everyone simply because one person stated it as opinion.
As such, there's nothing right or wrong with your (or anyone else's) opinion or perception either or how you interpreted the question, it just is what it is. Naturally, everyone will have differing and even conflicting perceptions and responses to such subjective questions and they're neither right or wrong either. Such is the nature of subjectivity.
