I love it, although I can see it being helpful only in limited scenarios, like CoD Zombies or other co-op type of game where it's common that you don't see your friend(s) on your own display, but other that that, I think it'll bring more distraction to your own gameplay rather than anything else.
Being able to 'snap' cards which show you a hint for the achievement is just 'blah' to me. I can't see myself using any of these trophy progress data stuff, or needed hints to be shown to me. I guess it's nicer that if you are stuck on a game, you don't have to start pulling up YouTube, finding a Let's Play, finding the right area of the game etc.
I'm more interested if we can pin our own bits there, like our previously captured videos from the Capture Gallery (if it still exists, not far into the video yet), so I can cross reference things fast without leaving the game I am in. That would stop me having to jump between game and Capture Gallery a lot.
If this feature allows you to stream you tube videos I could definitely see myself using this in games that have actions that are super repetitive. For example I spent over 30 minutes opening crates in division 2 where you just hold a button, wait for the animation to finish, press another button and repeat the same process over and over. I know a lot of players dont even bother opening the crates because they have so many keys that it would take hours for them to use them all.
As promised, PS4 allows to share gameplay through video streaming. The difference between PS4 and PS5 is that now you'll be able to watch this video while playing in a secondary window, instead of having to completely move to a separate app.
Maybe a friends wants to show you how to make certain combo, or where is some hidden stuff that isn't expained in these guides (and this is if the game supports these guide), or to coordinate stuff in multiplayer matches. Or maybe you want to see how a pro-gamer does his stuff. There are many possibilities.
It's a good feature but not something that I would personally ever use. When I play the game I want to focus on the gameplay and the gameplay only. Don't care about streamers, don't care about tips or achievements. Using it as an over the internet split screen sounds promising. Much better showcase than the example from the UI video demo (playing Sackboy while watching your friend watching Uncharted).
Maybe not you, but lots of gamers multitask these days. They game, they stream, they chat, they communicate, they surf and look for things on the internet during pauses and breaks. The great thing about all of these features is you don't have to use them if it proves detrimental to your gaming experience, but millions will use it. That's why choice and options are great.
Share play on ps4 was awesome and I was wondering how they'd improve on it. This is a bigger improvement then I expected. Very happy so far, I just hope the party chat system isn't exactly like it is on ps4.
