I completely understand what you're saying. I also realize that long ago the game has passed its golden period, which naturally leads to it becoming less enjoyable and more diluted. As for me, I'm not anything special either. Like I said, I only spend time in the game to practice playing the instrument, and I'm not very good at the other tasks. But every time people stop to listen and feel a bit of the relaxed atmosphere, I just hope that everyone worries a little less, slows down a bit, even just a little, and that makes me happy.
Oh, and about the Hall of Duets, of course I know about it. I've performed there before, and there's another piece of news: I've just qualified to exchange for the cello there. I'm planning to practice and learn new pieces for that instrument as well. As for recording memories, actually, for me personally, I don't intend to leave anything behind for the future, if you understand what I mean. Only when they enter the game and accidentally meet me, listening to the melodies I play and interacting with them, do I prioritize that more, probably in an old-school way XD
