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.
Apparently at Critter Depot, if you’re stateside. 2,000 crickets for $54. Subscription discounts available.
