Before checking out Girl by Moonlight last year, I had zero familiarity with the magical girl genre, and now I am two full 10-sesssion campaigns behind - one as a player (where I had a truly phenomenal and emotionally intense time), and another as a director (which I consider my current best GMing achievement), and soon I will be gearing up to run my second (and be in my overall third) campaign, one that I'm already confident in being my personal overall best TTRPG game yet.
There are some things I wish the game did differently or had more to it in places (wishing for a rules or playbook expansion someday!), but it is still really special - it wouldn't keep me interested for three campaigns straight otherwise.
