Somewhat rough around the edges but still the best adventure game of the year.
Pro:
* Deep and epic story, probably the most epic since The Longest Journey
* Lots of content, you won't finish this one in a single night
* Open ended, your decisions influence outcome (not radically but enough to make you care)
* Excellent voice acting
* Mostly good music
Con:
* Graphics could have been better for 2007, looks more like 2002-2005
* Navigation is somewhat cumbersome, it's hard to get to grips with the surroundings
* The interface is good looking but not very user friendly, trial and error takes ages
* Ending not as epic as you might think, there will be a sequal
* Lots or dialogue... I like lots of dialogue but this may be too much even for me, should have been balanced with more exploration
Sum:
Somewhat rough around the edges but still the best adventure game of the year, if you like the genre you should definitely play it. I would give it maybe 8.8 but I don't think it's really deserving of the full 9.0.
