It feels liberating to carry your entire game library with you and not in your gaming room. You can play games in many places, and emulation is just an icing to the cake. I have hundreds if not thousands of retro games (such as Parasite Eve, Marvel vs Capcom, Metal Gear Solid 3, classic Resident Evil games, Dino Crisis, Vagrant Story and much more) alongside modern games stored on it. I can play them in the bed, outdoor or whatever. Great for family gathering etc

Also able to watch Netflix, youtube and more on it, so why not.

I have modern consoles (Nintendo Switch, PS5, Xbox series S) and a RTX3070TI PC but I still spend lots of time on the Steam Deck.
