Superbly written; A Masterpiece
This game is one of my favorite games of all time. It is a joy to play. Sure the graphics aren't the best ever, and maybe the game would have looked better in 2d, not 3d..but regardless, Jane Jensen wrote a MAGNIFICENT story that makes this game more like a blockbuster movie or a thrilling novel. The gameplay is very fun, aside from some graphical glitches and bugs, but I didn't really mind them. There is a lot of witty humor incorporated in the dialogue, and the sound effects, music and voice acting is top notch.
Though it may not be a technical achievement like Oblivion or Half Life, Gabriel Knight 3 has THE BEST STORY I have ever seen in a computer game. GK 1 and 2 are also WONDERFUL, and I highly recommend them to anyone who enjoys an engrossing adventure.
