I'm so incredibly confused about the fact that people keep pretending the two Baldur's Gate were two exceptionally dark and grim games.
They weren't. Not in art style nor in tone or narrative.
They were basically your run-of-the-mill Saturday Morning Fantasy.
Planescape: Torment was a far, FAR darker and mature game both in tone and and visual style.
Hell, the entire premise of the Mind Flayers moving openly against cities of the Sword Coast is already fairly more cupe than most of what you experienced through an entire BG2 campaign and having them as the (at least at first) designed villains is already more intimidating of what the previous BG games were setting you up against.
EDIT: Also, not sure why people are assuming the game is going to remove reactions and stuff only after seeing one gameplay video with level 1 characters.
Again, I've only made this to collect info about how people (EDIT: or myself - I'm a human and thus selfish after all :P) feel in regards to each topic that seemed strongly discussed, not to start another discussion.
In regards to the reactions, it was said (I believe in an interview, check the relevant thread on reactions) that only AoO would be implemented to not slow down combat through appearing menus or whatever.
