TBH I don't really care about the scores. What matters to me most is that while ACII blew my mind back in the day, it's when the series dipped it's toes into RPG territory that I felt like it finally was complete. And yeah stealth was just as important, and even more effective and interesting thanks to bigger worlds and more varied methods of entry, hiding, distracting and killing. All laced with two things I love. Levelling up, and getting GEAR!
So yeah for us who loved Odyssey and Valhalla, Mirage does sound like a major step back. But it's not like all is lost, as Red will be more like the former than the latter.
And yeah I even loved the dark sheep, Assassin's Creed III. I love that game. But honestly using Valhalla as a base, and removing pieces to make it more like a classic style AC sounds good on paper, as like I said Odyssey and Valhalla really nailed that stealth. But many of the reviews really do make it sound like sadly, it didn't work out as well as it should have.
