Here is the camera zooming out during the boss fight with Belial. This feature has been in the game since 2012 and people are now talking about it like it's the most unbelievable thing the gaming industry has seen. People claiming D4 has a new engine is so fucking unbelievable and appalling to me that it makes me throw up by how easy it is for Blizzard to sell their lies.
You're entitled to your opinion, but...in the end who really gives a crap about what engine is being used? If the game is good, I could care less what software they use to make it. The graphic quality of the demo was far superior to D3 live, I don't care what engine it is, although the devs did say at the panel that it was new, if memory serves.
The way it was described (and was my experience on the demo), is that the gameplay should feel bleak-you're alone with no help, no reinforcements, most of the time. You will always solo dungeons, unless you choose to be in a party. In the towns, there will be more people, and there you can chat, trade, form groups, etc. In the open world, you\ll generally only see other players near a town or a world event, this is all done via phasing.
The grain of salt to take away from this is...it is still really early in the development, a lot can change and who knows in what direction. All we can do is keep providing feedback, and hope they listen.
And I will echo my 1st post in this thread; the gameplay videos do not do the graphics of the demo any justice. It looked as different from D3 as D3 did to D2, in my eyes anyway.
I'll share my thoughts here, I was lucky enough to go to Blizzcon and play the demo.
The game is not in any way a D3 reskin; the resolution is insanely better and more detailed, and there was a tremendous cut-scene as well. Stylistically, it is similar to D3, so I can see how a low res trailer may not look that great, and feel more like D3; it was awesome playing it live though.
As for all the negativity...well, you're entitled to how you feel, but I think it is OK for people to feel happy about how they are going about game design without telling them "it's not cool, we should have had it already!" It was fun to experience the announcement, and it is fun to watch as the game develops. This is just advice from an old person: life is better when you enjoy it for what it is, and not when you are miserable over what it isn't.
The open world aspect is not going to work like WoW, where you see hundreds of people all the time. For the most part, you will be alone unless you choose not to be; Sanctuary is dismal and bleak, and playing in small groups reinforces that. You will start to see players when you get near certain world bosses or events and towns (at least that was happened in my game), but you don't share loot or anything like that.
I'm concerned as well about the trading issue, but I think if we as a community keep the feedback going, it will at least force a reasonable explanation as to why certain items will only be BoP, and I think at the least, we should get them to be BoA, like they are now in D3. That said, we need to realize that duping ruined realm play on D2; if you played single player you avoided all that, but we won't have that lux in D4, and I'd rather not have the game be decided by cheaters.
As others said, we are so early in development, and so much can change. Remember that early D3 trailer back in 2008? A lot changed between that and release, so no reason to assume that a lot of things won't change by the time the game is ready for launch. As long as we keep providing constructive feedback, we have a shot at the game being what we want.
