The other factor for why console gaming is looked at with more nostalgia than PC gaming:
Console games tend to only look one way. But with each PC game, there tends to be variation. Most games have low, medium, high—sometimes ultra settings. And you can get even more granular. I’m not even considering mods.
When you look at a GameCube game, you tend to think, “That looks like a GameCube game”. Because of wide variations in hardware, no PC game looks uniform.
