An undiscovered gem - don't pass it up.
Gameplay - as I've already said, the relative inferiority of the plot compared with the BG series and the lack of the funny conversation known and loved from BGII and Throne of Bhaal bring this down, but other than that it's excellent, the new ruleset makes the game much more accessible and battles can be a lot more fun, so 8/10 seemed fair.
Graphics - utterly flawless. A lot of people don't seem to understand that much of the point of the Infinity Engine is that the 2-Dness of the game means that it relies upon hand-painted backgrounds, hence the better the background, the better the graphics. Since the developers have gone beyond the call of duty with the effort in drawing these, each area is stunning to behold, 10/10 here.
Sound - um, come on. From the splendid battle music right down to the delightful 'splat' when an enemy is cut to pieces, this is a clear 10, and it's what I expect with the brilliance of the BG and SoA soundtracks.
Value - I've seen this game (pre-owned, but it doesn't matter) in Gamestation for 99p. Can't say fairer than that, can I?
I just wish they'd made an Icewind Dale III...
