My answer to this question has changed radically many times over the years. Right now my ideal experience involves teamwork and growth.

Think Overcooked where you need to work as a team to maximise your potential. There are lots of games that pull that lever, but they all come with “frenetic chaotic physics-based ACTION” and im looking for more Stardew Valley/Arcade Paradise kind of energy where the better you do the faster/further youll improve, but there’s no real fail condition.

Drop in/drop out also very much desired as family members come and go as life allows.
