Broken Sword: The Sleeping Dragon is a very entertaining adventure game.
I know that there are those who dislike the 3D graphics (I was sceptic too at first), but I think it fits this game.
The game's difficulty is just right, which makes you feel like you are in a movie, since the story (which is long and takes you around the world) just unravels before your eyes. The story is as always very thrilling, and involves everything from gunfighting to infiltrating a medieval castle in the beautiful city of Prague.
For those who are fans of Indiana Jones (which I am), I can really recommend this game. It has everything that you can possibly want from a good adventure; a hero and his girlfriend, a criminal mastermind, and a diabolical plan to overtake the world.
The length of the game is really amazing. I've played it several times, and every time I am equally amazed when I come to a place or situation that I had totally forgotten about.
The only thing that I can think is less great than the rest of the game, is the fact that you sometimes have to sneak, in order to avoid guards, and that there are too many crate puzzle.
Other than that, this is a really, really great adventure game.
