A lot more info but not much clarity, sadly.
Also that is totally not how ceremorphosis works, and I say that as the sort of sad D&D nerd who instantly knew what ceremorphosis meant. The process takes a long time. Might as well advertise an Alien-based game with a dude just spontaneously changing into a full-grown xenomorph…
The only things we know now are that:
A) It’s set in the Forgotten Realms (the third-most generic D&D setting, after Greyhawk and Mystara - slightly more generic than Krynn/Dragonlance amazingly).
B) It’s set 100 years after BG1/2, which makes sense because the current FR is approximately 100 years on from that FR.
C) They will be using loosely based on the 5E ruleset, but not actually following the 5E rules.
To me this bodes ill, because both D:OS1 and D:OS2 are mechanically deeply flawed in ways that should be transparently obvious to half-decent game designers, but that Larian have not apparently noticed - they “fixed” D:OS2 by tweaking it very slightly and retaining all the major flaws in full force.
Still later he seems to backtrack a bit so maybe they’ll hew fairly close.
D) Multiplayer as expected - what form is unclear.
E) Party-based as expected.
F) On Stadia (to buy, not as part of the sub) as well as PC, but very much “as well as”, not as the primary thing.
G) Will involve Mindflayers in some serious way.
As long-time D&D DM, I’m curious to how they’ll work that. Low-level D&D can’t feature Mindflayers, so they’ll probably either have to massively re-work the rules, or start you at a moderate level (or rush you through the lower levels). Mindflayers are also kind of incredibly annoying to fight, because they stun and otherwise CC the party a lot, and so on. Plus they’re pretty one-note. More one-note than say, dragons or Beholders. But we’ll see.
What they’ve avoided doing in any interview or discussion is confirming that it is:
So my strong suspicion is that it is neither.
They’ve also repeatedly said that they’re doing some things no CRPG has ever really done before. So my guess, based on the refusal to confirm turn-based or isometric, heavy emphasis on multiplayer, the phrase “everyone is a hero” and talk about a “party of heroes” and so on, is that this will, by design, be designed to be at least 1-4 player real-time multiplayer, in third or first-person. There’s no doubt, with Larian, that they’ll allow for single-player, but I dunno why they’ve been avoiding confirming isometric or turn-based if it’s either of those things, given both would please 99% of the potential audience!
Interesting to note Larian are now a “full-size” studio - bigger than Bethesda Game Studios (the Elder Scrolls people), actually, at 300 people.
So I expect this will be aiming to be full AAA spectacle in the vein of a multiplayer Witcher 3 or something.
Honestly I remain mixed on this, and would have preferred a solid confirm of isometric, turn-based, and just simple co-op like D:OS2, but it sounds like we’re getting something a lot more ambitious and risky, which could be good - or not.
