If you like adventure games you'll enjoy this game.
It begins as drake uncovers a diary left by one of his ancestors which contains information on the lost treasure of El Dorado. So you set off on your adventure persued by baddies that also want your fortune ala Indiana Jones.
The environments are well done and detailed so that architecture and scenery come of as plausible. The story line is ok however it could have been a little more in depth seeing as the same writers of National Treasure penned up this script.
Prepare for a lot of shooting and climbing. During your adventure you'll have to fend of a bunch of thugs. The AI is hit or miss with them. Sometimes they were shooting in other directions, which is fine by me. They do get repetitive however since there are probably only about 5 different models for them, so you end up seeing a bunch of twins throughout your game.
The climbing portions are great. Not quite Prince of Persia however more realistic. I did die several times trying to jump and missing my mark but the check points seem to start you off nice and close to your mark until the very end.
Overall this game was a nice relaxing not too cerebral adventure which I finished in under 10 hours. The characters were all very well voiced which always makes a game more enjoyable.
