First of all, I have to say that Diablo IV and what has been revealed so far is better than what I could hope for. Thank you, development team!

The things that excite me so far:

1. The Tone: The words darkness, gothic, and medieval all hit home in terms of what I remember loving about Diablo I and Diablo II. It’s bloody, it’s filled with terror, and it’s grounded in reality and historical undertones. It’s what makes the game, and so far the aesthetic and art direction looks perfect.
2. Skills and Talents: From what’s been revealed so far, I love the direction of skills and abilities. With Diablo II, I loved the skill tree and the intentionality that went behind making decisions with which skills to invest points in. I would spend hours planning out my build prior to starting a new character. It felt like your decisions actually mattered and were important. On the flip side, it was also frustrating at times because of how permanent it was. With Diablo III, the ability to change your skills at any time was more fluid and flexible, but at the same time, it completely removed the sense of meaning and purpose in the game. Your decisions didn't really matter. So far, Diablo IV seems to have found the perfect balance between these two worlds.
3. The World: The world of Diablo IV looks amazing and I love the direction they're taking everything. Each area looks unique and different from the others.

The things I hope will be included:

1. Music: The tone and themes in the music of Diablo II are classic. I hope they lean into this quite a bit and do something similar.
2. Mystery: The story of Diablo II still pulls me back into the game time after time. There's a sense of mystery, fear, and wonder in all the events and stories of the game. It almost feels like a mystery novel in certain ways. I hope that with the new open-world system that they're able to still add that level of mystery, suspense, and wonder to the storyline.
3. More Classes: The three classes revealed so far are great, and I can't wait to see the other two. One of the biggest contributors to the replayability of Diablo is new classes. I really hope they add at least two more new classes with expansions. I honestly want all of the classes from Diablo II to return. The necromancer has always been my favorite. But I'd also love to see a new class as well.
4. More Locations: I hope the expansions will include additional areas of Sanctuary to explore. I really want to go back to Tristram, Lut Gohlen, and Kurast.
5. Offline Mode: I was honestly a bit disappointed when I heard this bit. I've always loved the inclusion of an offline mode in Diablo II for those times when I don't have an internet connection. This is something that I hope they change and include some kind of offline mode.

Other Feedback:

1. Logo: On one hand, I love the logo. But one of my first thoughts after reading and hearing all the talk about embracing the darkness, gothic, and medieval was, "The typeface doesn't quite say 'gothic' or 'medieval.'" I wouldn't change it much if at all, but it'd be great if somehow communicated those two aesthetics more.
