I feel this. I don't reach the same level of drain after playing compared to work. However, it's such a fun way to use my brain in a similar way, I can be hard to put it down.

I also find it rewarding after getting robotics and memorizing recipes. Which allows me to focus more on designing (I suck so bad at it but it's fun).

After a good few hundred hours I moved on to krastorio2 + space exploration. It's so much more complex.

Oh and multiplayer is a great addition allowing me to asynchronously play with some friends /colleagues.

Factorio is fun but the way I play it was unhealthy—several hours of Factorio after 7 hours of sitting in front of a computer. I had to give it up to find a healthier lifestyle—e.g. running, hiking, or taking a walk in nature.

I do want to come back to Factorio since it's an awesome game, but currently I cannot find the good timing for it.
