But a good game is good forever. Its just that a lot of these "console classics" were never good. Goldeneye was horseshit since the day it came out. It had some good ideas, on paper, but the implementation especially compared to pc games was horrid. Its just that consoles players didnt really have a frame of reference. Now, decades later, after console games eventually copied pc style games, of course we can all see Goldeneye for what it always was. It didnt transform into a bad game over the years - thats the game it always was.
In contrast, actual good games, Thief, Deus Ex 1, Half Life, Unreal Tournament and so on - the tech behind them has aged, sure. The gameplay and design of those is as strong today as it was when they came out. I can play Half Life today and its better than 99.99% of games out there. I can play Thief and its better than 100% of games out there. Outside of animation and stuff that has to do with tech aging, the gamedesign if ageless
