Actually, if anything, the delay worked against me. It was originally to be formatted in roughly the same way that the three Fourth Edition Ultimate Books (TUMA, TUM, TUSM) were formatted, written initially as The Ultimate Giant Robot but later expanding to The Ultimate Super Vehicle. Then Steve Peterson asked that it be made into The Ultimate Vehicle, to take away the appearance that it would apply just to superheroes, and asked that I include more stuff for low-end vehicles. Then there was a year or so of delay, and finally Bruce said it would become the first supplement for 5th Edition Hero but I needed to rewrite it in accordance with the rules Steve had rewritten and also include stuff for Fuzion. Then there was another long delay, Hero changed hands to Cybergames and then to DOJ, and around it came again -- I needed to rewrite it to fit the new Fifth Edition rules (not just Steve's review manuscript), take out the Fuzion stuff... and rearrange everything to the outline in the book as you now have it.
By this time, the only Fifth Edition book I had was the rulebook, and I'd only briefly gotten to glance inside the Champions genre book, so I was a bit confused as to how exactly to proceed. I did what I could, but Steve still had to cut a lot of what I wrote (only a little of that got into DH#7), add more material of his own writing, rearrange a lot of the text I'd written into the correct order (nearly all of the vehicle construction rules in Chapters Two through Seven are either moved from my Chapter One or written by Steve), add more sample Vehicles, and fix a whole lot of other stuff. In retrospect, if I were starting the manuscript today and had the other Hero books now in my possession (which is everything published so far except NH and TE), I would've come up on my own with something much closer to what Steve ended up with than what I actually turned in.
So, while I'll gladly take credit for 55% of the text in the book (which is about the percentage I got paid for, and rightly so) I have to give Steve at least 75% of the credit for how great the book is. Hopefully I'll be able to redeem myself with a better job performance with a future supplement. (There are a couple of "unassigned" books on the 2005 schedule that I'd drool over, but Steve won't let me start on them. )
