I appreciate your more detailed description. I think I get what you’re trying to explain. It just seems to me (at a very shallow level, I’m no expert) that all else being equal, 2D should be able to do just about anything that 3D can, but more simply (with some exceptions, of course - trying to reproduce a 3D look and behavior in 2D would obviously be an order of magnitude more work than just doing it in 3D).

To your point, I’ve generally noticed that bone-driven 2D animations tend to look kind of janky, like marionettes, but I didn’t think that it was a technical limitation as much as just the animators taking a lot more shortcuts. In other words, why would limb tweening be inherently more overly visible in 2D vs. 3D? It seems that it would be hard to do a pure comparison that controlled for other variables, but intuitively it seems to me that in a comparison that did control for those 2D would turn out easier to produce content for than 3D.

Again, to your point, I can understand that if we compared popular hand-drawn or pixel art 2D assets and environments with popular styles of 3D assets and environments in common usage, especially across indie games, 3D could very likely come out ahead in productivity.

Sorry if I have dragged this conversation out too long. I have an interest in game design/development and game art and hope to some day get into both myself with some small games, so this is a topic that I would very much like to have a solid understanding of so I can make the most efficient use of my time.
