You can create your own games, gameplay-stories and emotions in "Dreams".

Years ago, one demo inspired / fascinated the horror game P.T. (by Hideo Kojima) the world. Unfortunately, Konami delete the game and focused on smartphone and sports games. Konami wanted to keep all rights (Graphic-Engine, MGS, PT..). After that, Hideo Kojima founded his own studio and works with his team (Yoji Shinkawa, Norman Reedus ect) on "Death Stranding" for PS4. And now: One of the most innovative games of recent years -  "Dreams", the game brings you many possibilities and.. You can bring the PT-demo to life!

My question is: When is release ? This summer or later ??

No surprise considering Dreams is a Creativity Engine. Great to see though. Looking forward to seeing levels from pretty much every major title in the history of gaming once it is released. Very interested to see what people do with stuff like Jak and Daxter, Mario, Banjo-Kazooie, Concker, and so many others.

While it is impressive, I have noticed some assets in that clip being spammed a bit here and there. I find the other demo's/clips others have made from their own P.T look-alike to looking that bit better.

I am also very excited.

There are more new stuff here (Dead Space, Super Mario, ect): http://www.gamefront.de/archiv01-2019-gamefront/Dreams---Spiele-Demos-Dead-Space---Zelda---Sonic.html

I'd love to see Nintendo's comments on this

Other demos and clips from Dreams too? Because Dreams right now is just a recent beta, you can't expect complete and perfect works when people are barely starting to try it out. It will get better.

I've gandered at other clips from other copies of other existing games recently. I wouldn't lay claim to saying these are "masterworks", ahead of recent and pre-existing games, otherwise we'd have to give kudos to say, the UE Zelda fan remakes, but we know they've been given so little over the years. The current Zelda fan made "dream" for example looks almost like a Zelda game, but mixed with a platformer. 

Besides, it getting better is a matter of taste in quality. This is after all, a game designed to make mere dreams, not fully fledged games you can buy on your own, that rival the quality of other entire dev teams, writers and artists. 

2D platformers are some of the easiest to make game types.
Once this launches there will be a ton of super mario like attempts made.

I agree. But this is due to the fact that these levels are made in mere hours while those others from Unreal and Unity are made in weeks and months.

Is a Legend of Dragoon Remake possible? lol
