It wasn't a very big area, and you know they likely spent a few weeks making it playable to make people talk about it instead of the HK thing.
Here's a stream:
I saw part of that guy's first reaction video and got just plain too annoyed at his amnesia and tinted glasses towards D1, D2 and D3. "the darkest ever" and all that. "It's like a horror movie". Jeeze. Yes, because Marius in the asylum was a happy fluffy unicorn story? Adria boiling and shooting blood and dumping you in a cauldron of blood in D3 is light and poppy? Etc. He's also just plain an idiot in some of the games he's playing in this video. Didn't watch the whole thing but....Ugh.
Still, it's an interesting different vibe, it is more like D2 so far... We'll see. Lots in flux yet that he's treating as fact. "No sohulder slot! Oh my!" Yeah, no belt, boots or bracers, either - inventory is extremely limited right now - if it stays this way, no wonder they're avoiding sets - you can't wear a 6-piece set if there are only 5 slots. I'm not a huge fan of b eing forced to see other players in my game. And we'll have to wait and see how they monetize- expansions are great and I don't mind microtransactions for cosmetics, but...nothing's set in stone, years out.
