Bioshock sort of touches on technocracy, but its more post-apocalyptic. A game that spans the rise and fall of a "board of great geniuses" would be great.
but for you, my dear retard, i'll make an exception:
Reconstruction, followed by Jim Crow. The late 70s had a period of progressiveness, of openness, especially towards homosexuals. Then AIDS came, and that was all forgotten. The 80s were another dark age.
In the 90s we had another brief opening, but that too ended sooner than it started. We didn't pick up until the 2010s. By 2014/2015 progressiveness was on the way out, just in time for marriage equality to push through. And now, we are in another dark period and have been for a while.
Technocracy just follow wherever the wind blows. Progressiveness will come back, and hopefully we can push enough through that we'll be set for the next decade to come. That's really what it's all about - get as much done as fast as possible, so that it cannot all be reverted, no matter how hard conservatives try.
