Well I bought a lot of third party games because I like to play game portable and the steam deck wasnt available yet.
I also like the Nintendo boxes for the physical games. I think they look nice and I will always buy a third party game if I really like it. For example I bought enter the gungeon digital and it’s one of my favorite games, so I just had to have it physical.
But now with the steam deck I can have access to all my other libraries, so now I don’t feel so appealed to buy third party games on switch. Also saves a ton of money because your don’t have to pay the “Nintendo tax”.
