Personally I prefer to play every game on its original place but, some people like to play there favorite games everywhere.
It does not have to be the same game but, something really close to it , like pubg to call of duty.
Tell me what you think.
I'd rather play PS games on PS consoles simply because it's easier play games using controllers. I also like playing games on huge screen wherein I can see every little detail without squinting. PS games on mobile phones tend to be harder to play because of the screen size of the phone (I use a Samsung Note 8 which has a slightly bigger screen than most phones nowadays but the screen size is still not enough for some games) Though some games were optimized and made for mobile phones, the game feel doesn't reach the satisfaction compared to playing games on actual PS console.
Well, I am more of a PS and PC gamer and I need the keys and controls to navigate the game therefore I am biased on this.
As for me, I prefer to play games in whatever places I'm in. It is convenient if I could play my favorite game anywhere. Aside from thay, purchasing my own PlayStation seems to be expensive for me. If developer could finds ways to integrate PlayStation games into the mobile market then why not.
