Congrats! If you’re someone like me who owns a decent PC but no longer enjoys sitting in front of one, definitely get yourself a dock so you can hook it up to your TV. They cost around $30 and is a great investment. Just remember to take the casing off (if you use one) if you’re planning to have your games running at anything between 1080p to 4K, and use FSR to reduce the load. I find the Deck heats up a fair bit even in winter.
Owning a Steam Deck really got me back into gaming. I carry it to work to play during breaks and hook it back up to my TV when I get home.
Almost always digital on my tablet or phone these days (I have a Kindle too but just can’t get used to the display), but I’ll buy physical copies to keep and/or give away if I really like them.
