not to psychoanalise someone’s accidental journal/art project but perhaps the daily showcase of what they’re doing is pushing them to add more variety to their game choices?
I sure know if I were to decide to post a screenshot a day I probably would have more varied game choices than normal. Even if it’s a funny thing you do online the mere act of showing it to others adds a layer of performance, and it’d be a very boring performance to show myself playing picross touch or sudokucube 7 days in a row
