Perhaps I went a little too far, I'm not a fan of the space victory
But it ramps up at just the time I feel plain BTS speeds up too fast, the medieval period, and makes each period after that last just about as long as each other. It does make space race harder to attain. My other usual tweaks are to require 4 legendary cities for a
victory and no time victory (though it rarely gets to that point).
