Well- no easy questions for me I suppose!
Having seen the original versions of both games (4CTF and DNW), but not having seen the revised version of either, that's a little hard to answer.
I *can* say that my purpose for doing this revision was twofold.
Vigilance was my first published game (and in fact, the second d20 superhero game EVER, after only the Foundation). There were things about it I liked, and things I... didn't.
So, having been a "pro" for almost two years, I decided it was time to try and get everything right.
Secondly, was an attempt to allow those running a supers game to tap into all the great d20 modern products out there, including my own Blood line.
One thing we really liked (my publisher and I), was the fact that we already had a martial arts book (Blood and Fists) under our belts, and a military book (Blood and Guts), and that this book tied both those products together.
Of course this also applies to d20 Modern books I did NOT write, such as the great Martial Arts Mayhem and MPCs by the Game Mechanics, Urban Arcana, etc. etc.
I hope this helps.
