My introduction was the old Call to Power game. Still waiting for a Civ-like game that has a near-future age of gameplay. That was always the coolest part to me.
Feels like most of the similar games today are either historical/current or purely scifi. I like the transition point. To play out possible ways of advancing forward. How do we get from today to entering the stars? Those were fun scenarios to play out.
There’s a couple of mods for civ that covers this I know, but they’re all abandoned and somewhat buggy these days. Plus this sort of thing works best if the game is balanced around it to begin with.
Steam is untouchable until Gaben dies. Then God help us all.
