BackExpression of Skill
I've noticed that I'm drawn to disciplines and activities that have a strong element of skill expression. Especially those where the skill ceiling is high and highly visible.
I think it is very satisfying to improve at something. To achieve mastery. Personally, the grind is a very enjoyable part of life.
I have never really enjoyed games where too much is up to random chance (eg. gachas).
When I played League, I mained high skill ceiling champions like Riven, Camille, and Katarina. They're just more fun to play.
