I always had trouble skipping the "In the beginning" intro of Civilization 1 and the ship departure scene of the original Colonization, because it seemed random when they would finally accept my Escape press or mouse click.

Turns out the procedural world generation is done during those intros!

So the faster your system is (or the higher your cycles in DOSBox) the sooner that process is done and you're able to skip the intro.
