MS and Sony can push their handhelds, but I’m not looking for a locked down device to play games on. The reason the Steam Deck was such a sell for me was that it is a full PC. That I can do what I want with. I don’t want “mobile” or console gaming, because they have turned them into predatory micro-transaction mess.
Secret of Mana and its remake are both co-op once you unlock the second character.
