I was so looking forward to NWN2 – I loved the Baldur’s Gate & NWN series from Bioware; and to a lesser extent the Icewind Dale games. The pre-release hype implied this would be NWN with radically improved graphics, especially scenery, with a more BG feel to the game and interface and everyone expected such. Instead Obsidian seems to have scrapped the entire engine & toolset and rebuilt from scratch. However they recycled many voice scripts & background music from the original! So you get a new game engine that is basically similar to NWN on the surface, but which has no new features of any huge merit and a limited quality rendering for your character customisation and only limited new original sounds.
NWN2 also exhibits similar bugs to what NWN had, in fact on first release it had more originally but by the 5th Patch (1.03.840) it has reached a more acceptable level. Probably released too soon it is yet to be seen whether Obsidian (& Atari) have a genuine commitment to support the game long-term as considerable patching will still be required.
Graphically the game is visually impressive at the high level, but the poor customisation capability for characters, limited variety of interior terrain, poor spell effect graphics, and issues with frame rates undermine this. Obsidian may not offer any real support for PWs; and only limited MP support! As a NWN fan I am disappointed – apart from the overall first impression of the graphics it offers little over the original.
I purchased the LE primarily to get the extra Feat & Store Items in game, although the artwork book is also nice (but features spoilers). It is better than the UK version of the LE. You will need 6.5GB to install, and 7GB free space to play & patch).
