My thoughts:
The ingame art has gained more realistic detail, and the colors seem a bit more muted for a darker, grittier aesthetic. There's topless women statues in
Scosglen, so Blizzard is actually embracing the Mature rating (surprisingly).
They've scaled Tristram back down to its original tiny hamlet, which in a wide shot helps amplify its isolated feel.
I imagine they'll be announcing more classes over time, but it'd be interesting if they stuck to three and really
fleshed them out. Unlikely, though, since on the website they write, "The
first three champions are..." implying more to come.
With the Druid, we can probably expect to see the Assassin, too.
I wonder if they'll be bringing back the other D2 classes, who were effectively replaced in D3, like the Paladin (vs. Monk and Crusader) or Amazon (vs. Demon Hunter). Witch Doctor was the Necromancer replacement originally, but then they added the Necro to D3, so there's of course room for fantasy variation rather than strictly mechanical variation. I could see them doing this, since like with Tristram there's a big nostalgia factor that would get people very excited. What with all the clamor for a D2 Remaster.
They did a good job with Lilith as the main villain. I remember being interested in her lore from D3.
I wonder what happened to her 'husband', the angel.
Talents, Skill Points, Runes, and Legendary loot.
1.
Talents: Tree, WoW's pick one-out-of-three, or just a variation on D3's passive skills?
2.
Skill Points: Like D2's with synergy buffs? Sounds like they might be going away from scaling everything off your weapon like in D3.
3.
Runes: Skill runes like D3, or Rune Words like D2?
4.
Legendary loot: So D3 itemization? I hope they don't fall into the Set system of D3, which eliminated most build variation.
