The steam deck can handle every game on every system from the PS2 and back, most games on the switch and PS3, smattering of Xbox and 360 and everything on PC barring the most graphically intensive AAA titles. Recommendations on that potential scope can go on forever.

If you like Zelda there are a few titles regarded as “must play” in the series, including Ocarina of Time, Link to the Past, Twilight Princess and many more in the “A” tier of Zelda titles. You’ve got probably years of play time just in those.

I’ve got an anbernic RG351 and it runs everything from early N64 an older flawlessly, good battery life, decent screen and fairly good buttons, really good if you’re out and about because it’s nice and compact. I’ve also got a Steam Deck that does everything else and as a home console.
