I'm mostly taking this from comic books. Comics are usually divided Superman(1938), Flash(1956), and Watchmen(1986)
Also, the whole idea of CRPG renaissance is dumb since early and mid 90's had a lot of classic CRPG's.
Comic books is a silly comparison. The naming of ages for comic books represents sales numbers combined with nostalgia and second hand collectibles values. There is virtually zero comparison between the cRPG genre and the comic book industry.
While there is some nostalgia for the older cRPGs, computer ownership was low and cRPGs were a niche within a niche. Only in the late 90s did both computers and the internet become a mainstream activity & this is evidenced in the numbers of sales & marked success of Diablo as the great game changer for both popularity and era. For the next six years cRPGs were both the primary triple A game and the time when cRPGs reached the widest audience, culminating in the renown GOTY of Baldur's Gate 2.
One could argue the golden age is actually now in this regard with games like Skyrim, Dark Souls & Witcher 3 being regular hugely popular iconic games that are so popular even dullards know their name, these, however, are not really cRPGs in the p&p tradition but are derivatives.
No matter how much you desperately want to apply your own personal prestige to something, its not a Golden Age without wide sales numbers. The Golden Age of cinema was the 1930s- 1940s, not because that decade had the best movies, but because every man & his dog went to the movies & that was the time when cinema numbers were at their peak.
If it was just a matter of age then the 'Golden Age' of comics would have started in the late 19th Century:
As you can see, the art style is much more refined than the later quickly made superhero comics. The eras you refer to only relate to the super-hero genre, which only really started with Superman, even though fantastical characters had existed long before that:
In the UK, a comic book entitled Comic Cuts:
Ran from 1890 to 1953 & had over 3000 issues & yet no-one remembers it today & people of this generation would lament the 'popamole' nature of 'modern comics' (post-1930s) that were all pictures & hardly any words. The paragraph-based comic strips finally dying out in the 1960s. The Golden Age of British Comics is considered the 1930s because reading comics back then was the kid's television or, later, their internet.
