What I got the most out of the original work was the description of an actual campaign. What I needed/wanted was an actual example of what success looks like.
And that is what I would like to have most out of a new product. An example of what success looks like. But only if it is authentic. A fictional description of a campaign that did not happen, no matter how fun to read, isn't what I want to pay money for. So as the product is updated, please don't err into that zone in the name of updating.
After that was the advice as related to that campaign.
I enjoyed the characters and house rules, but they really didn't have a lot of value for me. There were enough character examples out there when I got the product that I just didn't need any more to help me build characters - even more so today. Although it would be fun to see how the characters developed if you wrote up 200-250-300-etc. House rules are always interesting to read, but I honestly don't feel any great need for additional rules for the Hero System today.
It is hard to put yourself in the shoes of a newer gamer. But I suspect that the GM advice and campaign example would still be at the top. Although I think more people would get value out of the characters than I would. They likely don't have a stack of Hero System products that would crush a vehicle as I do...
But at the time it was all about the advice and campaign sections. And that stuff really transcended the Hero System and applied across to other game systems.
Basically, what I got the most out of it was 'this is what right looks like' and 'this is how I made it happen'.
What I would like most from this product would be more of that. Descriptions of adventures and how they played out. You mention later that you have a log of the session by session history? Yeah, that is what I want.
Thanks,
Chad
