I use it to play pretty much whatever I want to play while I am away from the house. I use it to play Northgard in the evenings on the couch with my wife and I dock it to the TV to let the kids play Human Fall Flat, Brawlhalla, Untitled Goose Game and Golf With Your Friends.

It Lets me sit on the deck and play diablo while the kids are playing in the yard.

I am also an avid linux desktop user so I get to play all this stuff on my gaming PC when I get the chance as well.

I love this. My steam deck has been a life saver and all these changes also let’s me game on my desktop.
