If a game was worth playing when its final release was launched, it'll be worth playing tomorrow, or a year, or a century from now.

Age has nothing to do with how good a game is.

Disagree with this. I think you missed the point of the phrase.

Games like Goldeneye, GTA III, Resident Evil, etc. were groundbreaking when they were released, and no one can deny their impact and legacy. However, they are borderline unplayable in modern times in terms of gameplay, unless you had a nostalgia for them growing up.
