Is Factorio a true 2D game?

Question

Design

I played in factorio It's a
great game and all that, but I noticed one interesting moment

Everything seems to be done in 2d, buildings, conveyors, even beetles . diagonals, again, even the same bugs. But as soon as we reach the railway, my 2d thinking starts to fail. Here are the same directions of movement, but the way the train model turns is not included in this framework. Moreover, there is not just a view from above, but there is a certain perspective. If we recall the same OpenTTD, then there these same trains moved along certain trajectories and did not move beyond their borders



Is there a separate texture sprite created for each degree of rotation, or is it something else?

The description says that this is a game "within an endless 2D world". But maybe the world itself is 2D and the buildings on it are in 3D?

PS in game design, I'm 0, it just suddenly became insanely interesting

Answer 1

You described different things - gameplay and graphics.
Gameplay can be 2D - and in the same factorio it is exactly that - you can't build a factory ABOVE the factory.
But with 2D gameplay, no one forbids using 3D models rather than 2D sprites. And it won't affect the gameplay in any way.
