I still think it's pretty neat how Ghost Trick was animated

>To show how quirky these characters are we put a lot of effort into the animation. We spent time in making full body character models. What’s interesting is we made them in 3D first. Usually, people would use motion capture, but we didn’t want them to be super realistic so we didn’t go through the whole motion capture process. We made each of the 3D models by hand and hand animated to them. This gave them an element of quirkiness, weirdness, that bit of individual style. Once we had them in 3D we rendered them into the 2D sprites you’ve seen.

End result is how Ghost trick looks almost rotoscoped but nah they did all that shit by hand
