As far as the game in concerned, the sprites are all just 2D assets. The fact that those assets came from a 3d model during development has no effect on performance. They also do manual post-processing on most of the 2D renders.

Your wording can easily be read as them shipping 3d models and rendering them as 2d at runtime. It's a weird way to say the game is made up of 2d assets.

		I wish that were the case, then they'd have released the (original) 3D models!

		The post had me wondering if factorio had done like [1]Prodeus did where it's all 3D models, but by default is viewed as 2D sprite animations. [1]https://www.prodeusgame.com/website/index.php
