It's a much more condensed experience than either of these - 40-60 minutes per playthrough depending on playstyle.

Fun game btw.
But EUIII, EUIV, CKII, HoI? Considerably steeper learning curve, IMO! I've spent over a hundred hours just trying to take over Ireland (the traditionally newb scenario) in CKII.
I would not suggest jumping from a Civ to any Paradox title except Stellaris. There's enough of Paradox's goofiness in the space combat ("whaa... I slaughtered the enemy, how do I not get their planets... war exhaustion, wtf is that... oh that kind of makes sense") and lots of visual feedback to keep you interested without making you cry too much.
What a great game. There's a lot of mod content out there, but it all just felt off to me, so I never really explored outside of vanilla.
I hope Shining Rock's next game is along the same lines and as good, if not better!
Factorio also has a very satisfying train mini-game, with a focus on complex signaling and dynamic pathing. Thankfully, there are dials to tune down combat. I like to use the "rail world" preset, which disables enemy expansion.
