Wow so many questions.
Looks like they only have one row of quick action buttons. Can people modify the gui like NWN2?
No quick heal etc..
When the dm set traps / secret door DC it look like he was limited to a set amount of choices.
The monsters did not have hp bar on his screen so he could have a quick look at everyone on the battlefields current hps(maybe a option).
I did not see any option for him to quick talk through the monsters/items/placables. Can be done in NWN1.
Many more question, just some off the top of my head.
Do not like the DM can be seen and the threat even in a quick adventure game. I look forward to campaign video, that will be the one we all be waiting on.
