2) Are there any additional options to the difficulty settings besides the three standard settings?
3) Is it possible to pause the game during realtime exploration?
I’m so sorry, kanisatha! I did very badly on spotting answers to your questions.
1. I think I had the option to multiclass my companions, but as I was trying to hurry I just accepted the defaults so I’m not 100% sure. Probably safest to wait for confirmation from a more reliable source.
2. I didn’t see any options for fine-tuning difficulty settings beyond the three levels.
3. I always just press escape to pause and didn’t try to do anything different, so I’m afraid I don’t know if there are any changes here.
Just as a heads up to both of you on the first question -
There are screenshots of Jaheira being spec'ed as a Druid/Sorceror. So multiclassing for companions does seem to be confirmed.
