Fair, but at that point you’re arguing a technicality that most people don’t really care about.
And if you want to argue technicalities, then I CAN give you a game that was released for the Steam Deck by YOUR definition. Aperture Desk Job. Yes, it can be played by PCs as well, but it was developed with the intent of it being a showcase of the Steam Deck’s controls. You can’t argue it “wasn’t a Steam Deck” game if your definition of whether a game was for a certain platform is based on whether it was intended for that platform.
Not going to downvote you this time because you actually explained your position. Though your tone VERY much tempted me to do so anyway.
