Systems Depth Ages Better Than Graphics
Minecraft's graphics have never been impressive. Its appeal is systemic: the crafting logic, the world generation, the way different systems interact. These do not degrade over time because they are not dependent on graphical technology. A game whose primary appeal is that it looks remarkable is at constant risk from newer technology. A game whose primary appeal is that it thinks interestingly is not.
Narrative Quality Is Timeless
The Witcher 3's writing will not be surpassed by graphical updates to newer games. A well-written character is well-written regardless of polygon count. Games like Planescape: Torment and Baldur's Gate 2 remain recommended by serious gamers not because their graphics hold up — they do not — but because their writing does. Text is the most durable component of any narrative game.
Mechanical Elegance vs. Mechanical Innovation
Some games age poorly because their mechanics were innovative rather than elegant — they introduced a control scheme that felt novel in its context and feels dated without that context. Elegant mechanics, by contrast, were always optimal for their task: Tetris is not dated because rotating blocks to fill rows was never a fashionable approach, it was simply the correct one. Elegance is permanent in a way that novelty is not.
