I played Sea of Stars almost entirely on the Deck, and it is indeed almost the perfect Deck game. My only minor complaint is the overworld map is NOT scaled for small screens.

I bought a Steam Deck specifically because Falcom/XSEED/NISA REFUSE TO GIVE US SWITCH PORTS OF TRAILS IN THE SKY.

I WOULD LITERALLY BUY THEM ALL AGAIN TO PLAY ON THE SWITCH. BUT NOOOOOOOOOOOOOO.
