This is from the creator of PUBG, PlayerUnknown. He no longer works on PUBG, but has a slate of other games coming out soon. The first title, Preface: Undiscovered World, is a tech demo that uses machine learning on your GPU to generate Earth scale game worlds. I didn't play it, but I think that is literally all it is, it generates a world and you can run around in it.
Prologue is a game-focused evolution of that tech demo. Instead of an entire planet, it generates a world roughly 8km x 8km that is also much more detailed (compared to Preface). It is meant to be a survival base building game. I think the idea of randomly generated worlds with great detail is awesome, but from what I played in the demo, it wasn't anything special. It could be because I had some graphics settings turned down, but I don't think that is what the issue was. The world itself felt pretty generic. It looked like any other forest you could find in a video game, but the best comparison to it would be something like Arma or DayZ's forests, which is ironic since PU got his start on a Arma 3 mod.
The gameplay mechanics were nothing special either. Of course, it is still early in development so it's nowhere near as polished as it could be, but from what there is, it has very generic survival/craft mechanics.
It could be a lot better, and perhaps it will evolve to be so, but for now I was left thoroughly unimpressed, yet still interested in it's development. The level of detail is what needs to set this apart because there are lots of games that generate worlds for you (Minecraft, 7 Days to Die, etc.), so for it to generate a fairly generic looking forest does not bode well for it's success. It would need to generate much more believable forests with lots of debris scattered about, add interesting locations like caves and other phenomenal land formations, overall it needs to be a lot better. It does not help that you are not given any controls to configure parameters either, unlike most other games that generate worlds for you.
