You can't really remake something that never got made in the first place, the Original BBS barely got much further than proof of concept.
This games first version just a Mod of BBS (same characters but more assertive MC), Now he is making his own game, he is making changes, making it his own, Characters are getting redesigned, and many of the plot points have changed, gone beyond the points the original reached. A lot of the Art is the same, but then this same art is reused in a significant percentage of Daz games out there.
