I have both a steam deck and a PS5. In my opinion there are so few exclusive titles any more that it’s not necessary to own both.
The one limitation is that the steam deck doesn’t have the performance to play some titles well.
For example, the PS5 is better for AAA titles like God of War, Horizon Zero Dawn, and Elden Ring.
The steam deck can play GoW, Horizon, and Elden Ring but you have to set the graphics quality very low and expect you’re only going to get like 24fps max. Whereas the PS5 will smash pixels all day long.
I mainly play indie games on my steam deck and AAA titles/exclusives on the PS5.
Does it have to be roof-mounted?
