It's not pixel-art. All their "entities" are actually 3d models that are rendered into isometric images. And they've also slowly been regenerating all their images with high-resolution models + renders.

It’s rendered to fixed resolution sprites. That’s pixel art.

Pixel art by definition involves the careful hand placement of individual pixels to create an image. What you are talking about is just a 2D game.

Which makes it better than the 3D you yearn for. You can't do as high-quality and as stylistically consistent graphics with real-time 3D rendering; the computing power simply isn't there.

Pixel art means making a picture while zoomed in to see individual pixels, placing them manually nearly pixel by pixel (only the most basic shape tools are used, and no anti aliasing).

Most importantly: Dithering by hand.

Play Satisfactory then.
