Sci-Fi are probably the worst genre for Erotic games. End ends up concentration on every other aspect beside the actual porn(and characters, places and outfits looking weird). And while there are a lot of BB remakes, they all tend to actually have less content then the original one for some reason, despite having years and years of times for new development and tons of fanarts and ideas going around.
remakes having less content are probably (IMO) due to support not being there as much as the original, and instead of putting in the work and getting it done, all they do is milk the few supporters they have as much as possible for the little they can get
plus the original one had pretty decent renders, and remakes have just small improvements here and there, basically no animations, plus you already know the story more or less, so the interest because of the story has simply faded away, and add the stupid grind to that and people just lose all interest
the NTR orientated remake was different, dev released it in basically 2 hits, the whole original story I mean, made from scratch, and was quick with patching few broken things, NTR isn't my thing so I haven't followed further development, but there was talk of animations and extended scenes or something like that, not sure if he captured the audience and gained support to continue the work
so, if you have all the assets to do it, can release a complete story quickly, doesn't have to be long, but has to be complete, then there probably will be people who will support that sort of thing, but if it turns out to be another blueballfest or 10 scenes with 500 renders, which turn out to be a couple 5sec animations which consist of 1sec looped 5 times, which add to 300 renders alone, then a scene is considered exchanging couple dialog lines with a character or two which doesn't even push the main story along, and that turns out to be maybe 5min of gameplay released every 4-5 months or so, all buggy and shit, then forget it, don't even start
