I'm part of the club! Although tbf I haven't touched it much since getting it about a year ago (I just haven't played that much retro stuff these days or most of it has been with my Super Nt).
One great addition I got recently was a 3D printed grip case, it made long play sessions sooo much more comfortable (obligatory "not affiliated" and I'm not the one making these, but I really like the quality which is why I'm linking it here).

As far as what I've been playing on it recently... really just pick up and play, SoR 2 or Turtles in Time, but I completed Metroid Fusion (first time) a few months ago on the Pocket (that's what made me get a grip case, it really wasn't too great wrt shoulder buttons comfort).
