I get what you’re saying - some games aren’t fun on steam deck controls, or just run like a dog.
But, look at it differently - It’s a PC by virtue of the fact you only have to buy it once to use it in both. My 10 year old XPS laptop and my gaming desktop are very different classes of hardware as well, but they’ll both run Plants vs Zombies that I bought once.
I can’t say that about the stuff I bought on Switch and want to keep playing on Steam Deck.
True story: I met Gwen this week and she gave me Molasses cookies. We’re all part of the Walz family now.
