I've seen his videos before - not a lot, but some - and I've never seen him give such praise. It went beyond just - "Yes, this is a good mechanic." I think he was actually having a lot of FUN - which translated in tone and the fact that he didn't speak quite so much about the game as I've seen him in the past.
As I said - I have not watched a great many of his videos.
I was so glad he was pretty much gushing over the game. He stated that the tactical mode was just like DA:O (I'm sure it's not "just like" but it evoked the feeling for him). He enjoyed the idea that he could roam about. He liked how tough Cassandra was (I just took this as a hint that he found her capacity to survive ample).
Concering Nightmare - he was hardly truly playing. He never stopped for tactical mode... never switched characters... never really strategized and he still did pretty well on nightmare. I loved how the boss intelligently handled the party. I read on the forums that the mobs on Nightmare don't act any more intelligent... this boss was plenty intelligent and I was VERY pleased with the challenge.
He had high praise for the seemless nature of the cinematics - he liked that it popped up "X approves" without a number (enough to make a note that it occurs at least).
Overrall - anyone who puts stock into him as a reviewer - his first video gave the game great remarks.
