Wo ist das vedammte Meer? Where is the fking oean?
i have a mid end specs pc (ryzen5600 and a RTX 3050) i left the game running for 30 min straight on the millennium falcon speed. the game didn't crash, i had very good frames even in the dense forest, the world was generating perfectly, and even though it probably wasn't the main focus i enjoyed the sound effects generations a lot, some birds and water sources being generated with the terrain. if we put in the idea of a bunch of buildings and roads being randomly generated along the topography you guys have a the most innovative game I've seen in a long time. the gaming community is in deep need of this. keep up the great work!

keen to see it develop
For gamers: this is NOT a game. This is a tech demo. For game developers: the demo is nice, but for now it's nothing really exciting. As far as I got it, it's just a procedurally generated world, shared across all the players. The tech is not really impressive from what I can see, the question is how much underlying stuff was already implemented. Really excited to see how it will go with actual gameplay in Prologue.
Игра 'Preface: Undiscovered World' - это захватывающее приключение, которое с первых минут погружает в атмосферу неизведанного. Визуальный стиль игры, выполненный в пиксельной ретро-эстетике, очаровывает и вызывает ностальгию. Сюжет, хоть и не поражает сложностью, увлекает своей загадочностью и предлагает игроку самому раскрывать тайны этого странного мира. Геймплей сосредоточен на исследовании территорий, сборе ресурсов и строительстве базы. Важным аспектом является выживание, требующее грамотного планирования и управления найденными ресурсами. Иногда игра кажется слегка затянутой из-за монотонности некоторых действий, но постепенное продвижение и открытие новых технологий скрашивают это впечатление. Отдельно хочется отметить атмосферное музыкальное сопровождение, которое идеально дополняет визуальный стиль и создает нужное настроение во время исследования. Для любителей игр на выживание с элементами крафтинга и ретро-графикой, 'Preface: Undiscovered World' может стать отличным выбором. Не шедевр, но крепкий и увлекательный проект, способный подарить несколько часов интересного геймплея.
Its gotten better over the year
What is this? There is no variation to anything, just slightly different colors.
This is a cool tech demo and a good start to this project. shows the potential but definitely needs more work. For the developers I have a few recommendations or issues. 1. is adding collisions with rocks and trees. this will make it more immersive but will also show if this platform could actually withstand it. 2. increased render distance and better transitions in LOD. I can clearly see where it goes from normal detail to bad where its just the top of the tree with no detail and then no trees. Any area where you are on or near a hill/mountain you cannot see trees lower on the mountain or on the mountain if you are at the bottom. and if you go into periscope view you can only see a small circle of trees around you. This is by far probably the biggest thing that needs work. 3. jumping, this will be needed if rocks get collision, also just weird to not have this in any game. 4, diversit. 5, there is some weird colored ground in some areas like blue or red and areas that are sand when up close but green from a distance, just looks weird. also some mountains are super steep but still have boulders just sitting on the side and some trees on the cliffs, mostly just some terrain and render distance issues. But I see some huge possibilities with this game. There is some gorgeous areas and the landscape and terrain elevations are absolutely insane. it shows some potential for the future and the survival game they are making.
Kinda iffy on this game. Installed it on the old computer and it wouldn't even run. Installed it on the new computer, and the command window opened with red and white letters saying something about the game crashing, then Nortan popped up with a firewall alert. Finally got to play it, and so far nothing too interesting. You CAN walk through most solid matter, tho. That's cool. It does have pretty nice scenery, ngl. I would use this game as mostly a relaxer.
Pretty Pointless as it is but intresting to come and check it back from time to time
