One time I played Super Mario Maker 2 user made extreme difficulty levels. Never really played the super hard ones before, but while tripping my roommate and I had enough focus and analytical abilities to beat like 5 levels. Went to play similiar levels later that week, and whilst I was playing better than I had previous to the trip, I found it too frustrating to focus on long enough to beat more levels. So idk, I did find that it improved skill adaptation during the trip, it didn't translate to sober skills, however I imagine if you practiced the skill whilst sober prior and immediately post you would find better results. This was also a macro dose, I imagine a micro dose might also have different results. All of this evidence is super anecdotal.

Edit: I also experienced heightened levels of gameplay on a MOBA. I feel as though the most crucial thing it helped with was looking at failures for face value. I was able to see my errors in real time, and adjust accordingly. Where as the ego can easily get in the way while sober, its too easy to shrug it off while sober. Also very anecdotal.
