While I will continue to pine away for the next NWN2 with fully scriptable worlds and persistent servers, alas that is not to be. But that said, I am still excited about the DOS2 GM mode for what it is. And while I know this is going to be somewhat limited and require an active and accomplished GM, there are a couple basic things that I think would really help and perhaps are not too difficult to include.
Transitions
I think would go a long way to making the GM's job easier and also vastly improve immersion. You need a transition object and/or a transition element attached to a variety of objects where you link the transition. Include a transition on/off switch so the GM can activate and deactivate the transitions in the scene.
Vignette Launch
Similar to a transition, linking a Vignette to an object launches the linked Vignette. Closing a Vignette returns to the last scene. Again, being able to activate and deactivate the Vignette launches for a scene would be great.
Are we still doing new stretch goals ...
