Maybe this is a little weird but I actually use mine the most at the gym while on the treadmill and stair machine. It's helped me stay motivated to keep going back semi-regularly and luckily over the last year I've lost most of the weight I gained during the pandemic. I've also worked through a lot of games that have been sitting untouched in my library, especially those smaller indie games that run well on the Deck.
Apart from that I also bring it to family gatherings since it's convenient for local multiplayer games like Jackbox.
I don't know if I can call it garbage but probably no one in their right mind should play Hearts of Iron IV. Somehow I managed to persist through hours of bewilderment and confusion, until it all clicked, and I soon found myself unhealthily obsessed and unable to rest peacefully until glorious France had swept across half of the globe
