Actually, just FYI and just for completeness of information; StS and basically any computer game on PC or Mac, has been available for stream play for many years now by via other apps such as Splashtop, chrome Remote Desktop, VNC viewer, and team viewer. Steam link actually does little more than those apps, and they’ve been around for years. They even all 4G internet play, which steam link is only just about to allow (if not already?? It did in the beta). Also, some of those apps imo offer a better control scheme.
I’ve been using Splashtop with my Mac and iPhone for about a year now and settled on it because I liked the way it simulated the mouse control.
Basically any “mouse only” input game that is turn based can be played using these apps quite well. I play StS and Into The Breach remotely to my Xs Max.
Anyway. Yes. StS is incredible and I can’t wait till it releases on phone supposedly later this year. Until then, on iOS there’s Dream Quest, night of the full moon, pirates outlaws, Card Quest, lophis roguelike, dimensions of dream, spellsword origins, Silent Abyss and Royal booty Quest (is a clone of StS with terrible graphics and some changes up basically because they just couldn’t quite copy it completely in all its intracies).
