I do have PDF ... less than 2 weeks ago Marc sent it to the inner circle. Robject and I both are in that group.
I have only skimmed it, and only looked at a few sections.
T5 starts with a pair of what are, for me, fatal flaws - using the multi-die task system and the 1 skill level per year.
Honestly, and certainly insight in to the actual systems is important, but I think more important is simply the production quality of the set.
While, perhaps, you may not like the task system, is it well explained, at the examples of its use accurate, etc.?
I know a lot of folks have commented on the systems themselves, but there's also been the comments on just the simple quality of the production.
I recall getting T4, I was pretty excited. Bought 2 copies. Then I got FF&S for T4, which was a complete and utter disaster. Someone dropped the ball on that. Not only did they drop the ball, they just stood there and stared at it as the runners cleared the bases.
And that killed T4 mostly for me, I never really gave it a second look. Then the early reviews of T5 came out and the T4 episode just rang in my head to where I didn't even look at it once.
Presentation matters, at least to me. A bad system presented well, documented, etc. is better than a bad presentation of a good system to where the production overshadows the underlying content.
Early Dr. Who is like that to me. I can't watch, I don't know if the stories are good or not honestly, the production was just so terrible. I know, that perhaps that's part of the appeal perhaps to some, but it was off putting enough to me to not give it a second glance.
It's honestly beyond disappointing that someone who I thought (mistakenly?) would be on the inner circle still has skepticism about fundamentals within it. As if baseline commentary was not necessarily addressed. It's not that I don't recognize the size and scope of this project, but, honestly, it's been a LONG time.
That's what I feel, I obviously don't know.
