This is highly subjective so probably some people will strongly disagree, but I do think there have been significantly better and worse "ages" in videogames. It's not been constant progress.
For example, I'd say 1999-2005 was a quite crappy age. Dominant consoles were Playstation 1 and 2, the first XBox and the Game Cube, which of course had some fine outlier games but nothing compared to the mind-blowing catalogs of e.g. the SNES or the Neo Geo, which were brimming with gems, many of them are still widely considered among the best games of all time.
In the PC, after breakthrough games in the previous years like Daggerfall, Quake, Master of Magic, Doom, Civ II, Ultima Underworld, Fallout, Warcraft, Starcraft, GTA, etc., most of what dominated the market in that decadence period were sequels of those and others, and unoriginal games.
This opinion is not just due to my being a cranky old timer wanting people to get off his lawn. I do think the situation improved a lot from 2006 onwards. Team Fortress II, the Wii, Portal, Minecraft... were truly revolutionary concepts in the late 2000s in different ways, and indie games began to flourish with titles like World of Goo or Braid (or said Minecraft). Fast forward to now, and we have the Switch, Pokémon Go (geolocation games), and a blooming indie universe. I do think we are at a golden age, it would be a great time to be 15 again and have lots of time for videogames.
