Likeability is subjective

Camera fix is needed

Stealth: yes NPC should respond better. But you should be able to choose which of characters join the fight from stealth and when. I wouldn't change that

Venders: I end up with so many health pots etc anyway...they restock after every long rest, when each character levels up as well. I expect there will be alot more in BG (ie in a city and not in a wilderness).

Different colours/ designs for equipment would be great.

Party size has been mentioned. 4 is fine with me.

More companions would be nice (in addition to karlach minsc jaheria). A small furry one would be nice.
