Jez, what's the use case for this? I would think, but maybe wrongly, that the number of people who both buy a game and then would prefer to play it via streaming rather than locally is tiny. No?
For the person who owns a gaming system and has paid full price for the game, I would expect he or she would rather play locally for the improved performance compared with streaming. Maybe occasionally while travelling there would be good opportunities for playing those owned games, but while on the road, casual games tend to be a better fit (simply because big Xbox and PS games tend to draw play for hours at a time, and road warriors rarely have hours to play).
And for the person who doesn't own a gaming system, they're unlikely to want to buy the game in the first place.
So this seems a very niche application: PS5 game owners who travel a lot and like to play their PS5 games while on the road instead of casual mobile-friendly games.
Am I missing something?
