I gave it a 6.5 flat because that was my overall opinion of it. I'd honestly prefer those other metrics weren't used because when looking at them individually, yes their average is higher, but they aren't indicative of the whole. Just my take on it, not meant to be inflammatory.
I was going to mention Persona, but we know so little about it right now I didn't have much to go on. Christmas might come early if that teaser site reveals anything good on the 24th though!
I did after I finished it on normal. Wanted to get familiar with it first =)
