Gameplay wise, they're about as 3D as Fatal Fury on the Neo Geo was.
Ah, so you don't know what you're talking about. Got it. At least I know the "depth" of your gaming experience, and it explains everything above pretty well. Fatal Fury uses lanes, not 3D movement. Very fun series, by the way.
You can pull off fast gameplay with gamepads in 2D games. Actually controlling 3D movement? Not so much.
Funny, because 3D
movement with analog controls is infinitely more nuanced and precise than WASD. 3rd-person action games were popularized on console. Why is that? Wait... let me take a wild guess: was it The Filthy Casuals?
You still haven't done any of the following:
1. Supported your own claim that gamepads are holding back AI in 3D games by referencing a PC game that is your standard.
2. Supported your own claim that Ninja Gaiden, Bayonetta, (and other Japanese games) aren't challenging by referencing a 3rd-person PC game that is your standard.
3. Supported your own claims as to what a "true PC game" is.
4. Supported your own claims that the 3D fighting games I listed aren't 3D even though they have movement on the 3D plane.
5. Supported your own claims that controllers are too slow to handle "3rd person 3D game with truly aggressive, fast, and tough AI".
I grew up with PCs, long before I got into consoles. I'm pretty familiar with the strengths and weaknesses of the platform. Ultra-Fast-paced games only became a thing on PC mid-90s onward (when RTSs and FPSs began to take advantage of mouse controls). You have decades of gaming before and since to account for. Either take the L or take the time to explain your stance with actual facts.
