Some people were asking for impressions in the other thread so here are mine:
Game runs flawlessly on my machine (though there have been compatibility issues mentioned w/ crashes on launch, problems with the OpenGL support or lack thereof w/ Intel integrated graphics chips, and so forth).
Runs full screen or windowed, supports widescreen.
There's a new pretty good (optional) tutorial that will run you through game mechanics, concepts, and ideas.
I am really excited by the new NPCs that feel slotted in very naturally.
Black Pits is a completely standalone "adventure" that you launch from a separate menu on the title screen.
I know there have been complaints that many of the improvements found in this release can be accomplished w/ mods and fan compilations, but you know what? I don't want to fuck with any of that.
This, I installed, it worked, and it looked good "out of the box". Furthermore, it's supported by a development team that is still working on ironing out any bugs or issues that pop up.
If you've never played Baldur's Gate before, and don't want to deal with fiddling with mods, I easily recommend this version over just the GOG releases.
