There's many really interesting stories out there just waiting for some developer to make into a game...
Seriously doubt BB is one of them to begin with, but it had many fans despite its shallow story... So the original dev did something good, or the competition was even worse back in those days... Perhaps it was more original then...
You're not making it easy for yourself... Your game has to be better then all the fan made clones and be approximately as good as the original, but you really can't change too much about the original story, without disappointing the hardcore BB fans...
And to be fair, that's exactly the people who will be the main followers of your game... Most of the people that didn't like it back then simply will not like it now... Maybe some sandbox haters can be interested now, but a rework of the original into AVN does that that too... And there's many great games with great stories these days.... You'll have to compete with those as well...
End of rant....

And good luck, you will need it! But i applaud you for your courage to bring yet another fan made BB...
