If I were to give my own opinion, I’d definitely put my vote on the late 90s; that time was the stuff of legends, with ‘98 in particular being gaming’s absolute apex. Can’t think of any period before or after that equals that sheer amount of industry-shaking games that’re still sticking around today (Ocarina, FF7, StarCraft, DDR, etc). The mid 90s get a close second, and Mario 64 alone is a good reason for that.
I definitely have a fondness for the early 00s since the games still maintained an element of inventiveness even when the production teams got bigger, and they held onto that a bit into the mid 00s, but afterward, I feel like things got too big and the sense of individual voices faded; they started putting so much money into games that they got less risky for the sake of making back their budgets, and even bigger production teams means more people have to agree on any given aspect to keep the production momentum, hence the loss of a sense of voice.
