So I'm getting used to the layout and controls. I know this isn't BG 1 or 2, but there are a few things that stand out as not being as fun:
1. Why such a small party? 6 people was much more ideal.
2. Why no party formation? People wander into things like acid on the ground while trying to follow my character. Not only was there a party formation choice in the first two that had the party follow the exact steps of the leader, but the different formations spread the party out and exposed more map area as the progressed.
3. The camera. This is usually OK, but becomes horrible and unusable in narrow hallways or tunnels. And it needs to zoom out farther for a bigger overview of a battle. I spend more time trying to get the camera in a place where I can see everybody and get a tactical view than I do fighting sometimes.
So far, this is a pretty sweet game, but there are some components that made the first two games really fun and immersive, and they would help here. But I see where you guys are going with this, and I get it. There are just a few things missing, IMHO.
1 - Also prefer a larger party size, but in that respect, have you tried to play a D&D game with 6+ PC's? it's a nightmare sometimes, with everyone talking over or interrupting each other for actions, dialogue etc. So the smaller party makes sense.
2 - This is an issue. please correct

These are smart humanoid adults, they should know better than to walk through fire when there's a clear path set for them (plus you did this correctly in DOS:2, so it should be an easy fix right?)
3- I'm sure you already found this out, but there is a 'tactical view' button (I think it is defaulted to "O"?) That might be exactly what you're looking for to get a 'birds' eye view'
