(I am the developer of ExploJudo, this is my other personal account I use for my personal projects) yeah, unfortunately among indies 3D fighters are super rare, most if not all are 2D or 2.5D. I have made a full 3D fighter before called Schwarzerblitz, that was my love letter to that 90s genre :) the only big games left in this subgenre are Tekken, Soulcalibur and Dead or Alive. I wish things can change, but it looks hard...
