As a PC gamer I have to disagree with you.
I think the "golden age" of games was between the mid-90s and early 00s.
At that time, the variety, especially on the AAA market, was so much higher than it is today, and it was also a time of great inventions. Think of 3D Engines, RTS, FPS, Online Multiplayer, all these things started there.
The amount of classics from that period is crazy:
Half Life 1 and 2
Counter Strike
Unreal
Quake
Thief
Deus Ex
System Shock 2
Planescape: Torment
Baldur's Gate 2
Fallout 2
Comand and Conquer
Diablo 2
Star Craft
War Craft 3
AoE 2
and that's just the PC-Games.
