Thanks for the warm welcome.
Witch trainer was my first "trainer" game, and despite some grindy game mechanics become my favourite game.
Generally I was mostly dissapointed by all available "mods" for original Witch trainer, despite that some improving some aspects of original game. In some moment SadCrab finnish with modding and started creating new game "Innocent Witches" - it have nice graphics, same enviro setup, but somehow I lack some "magic" of original.
I bought VR and after HF:Alyx realized, that there is not much to do with VR, but I found some simple erotic games which experiment with VR possibilities. I also tried V-A-M and this is where I do not agree with you - technology is already here, despite being still in development. Original Witch trainer is basically one room setup, which is ideal for VR. Even Hermione character and some other Hogward´s gilrs 3D models are available. I also tried one simple game in V-A-M where you triggered different scenes via dialog bubbles. So basically I´m convinced it would be possible to do it.
