Following are some questions I've been wondering about.
1. Type of modding (see Destello's post above)
- Can we make our own adventures like in NWN2?
Yes. This was confirmed within The Editor video showing the toolset in use but we knew this before then too.
FYI this could also be done in NWN1...
3. Stretch goals & the Editor -- How would the various stretch goals affect the editor capabilities?
- it was mentioned that schedules should be an entire system, which would, I imagine, require special programming. So, without the schedule stretch goal -- no schedules in mods either?
- could we in theory make custom personality traits with or without that stretch goal?
I'm going to guess here and say yes. Modders for Neverwinter Nights 1 added 24/7 schedules for NPC's in custom mods. It's all down to scripting. This means they would need to add in their own day and night system though if Larian doesn't...
But come on Larian that should be a feature regardless. Divine Divinity had it...
