I don't think so. Steam, for example, supports mods directly from the Steam client. Many of the games I play specifically support mods from within the game itself, integrated with this Steam mod functionality, and it even takes care of upgrades, dependencies and such.

There's a thriving ecosystem of games and mods out there, no such thing as a golden age that has ended.

Starcraft II for example has a host of excellent mods. My group doesn't even play the original Starcraft game, and I don't have any interest in it either, but we have sunk many hours into different custom maps.
