It must have to do with goals, if he wanted a game with more animations ...
Depending on hardware, time and personnel to make, and top invested money ..
If he does everything himself ,in 3 chapters it will be another one in the burnout line.
Even silly animations take a long time in Daz studio (I don't know with the new RTX or Quadro)
AniMate in Daz studio is not advancing much, you see genesis 3 assets still in use..for the scene to be perfect 215 frames .
A good sync is necessary, or the movements end up out of place and skipping frames with the face of Gif.
And maybe it ended like that, an ambitious project that on paper was fantastic, but in practice unviable .. (for now)
