Definitely. A sillier example, I find Minecraft can be useful to get me back in the zone if I'm feeling unfocused. Building systems and overcoming design limitations does require thought. Having to concentrate on something that's easy to concentrate on helps get you in the right "mode" so to speak.

Reddit, however, I find draining. There's always a risk of getting sea lioned by a particularly toxic user. Conversation tends to be very one-sided also.
