I think I last played on mine last summer, when Octopath Traveler came out. Played quite a bit of that for a couple of weeks and then simply haven't returned. I never expected to have a huge Switch collection, but I'm still a bit disappointed in the library besides the obviously awesome 1st party titles which I already own.
