Indeed, the Fan Day was great fun. And I have to agree with Helena, the quest-designing was very nice; if it'll survive until the actual game is released... well, we'll just have to wait and see.
Some additional snippets of information I seem to recall:
- *maybe* they'll add a player log to D: OS where you can add notes of your own
- almost all of the NPC's can be killed; apparently, we'll be able to finish the game by killing everyone (although obviously you'll miss out on a lot of side quests etc.)
- level cap hasn't been set yet, but gaining a level will always be and feel meaningful
- the environment will *not* scale with the player(s)' level (so exploring can be rewarding yet dangerous)
- originally, D: OS was planned as 4-player co-op; however, they quickly dropped that idea once they realised how much work that would add to the conversations alone...
- each type of animal has some kind of favourite food: mice and rats like cheese, horses and deer like apples, etc.
- if I recall correctly, the release window for D: OS is "Winter" (adding a whole new dimension to the phrase "Winter is coming"

)
- Swen mentioned something about the Alpha release – that will probably be somewhere in September
- ** warning: small spoilers ** the Messages in the Wood will in fact be engraved in one HUGE tree; otherwise they would have to add close to 20K trees

; what's more, this tree will also be the entrance to the Lair beneath the Phantom Forest
- related trivia: Divine Divinity, Beyond Divinity *and* Divinity II were originally intended as multiplayer
- apparently, Larian keeps doing "Divinity" prequels because they don't want to release Divinity III yet
And finally, everyone @Larian's was extremely nice! Swen even gave me his phone number so I could give him a ring if my hote;s reception turned out to be closed (that wasn't the case, by the way).
