As a huge fan of both the recent Lego games and Pirates of the Caribbean, I decided this game had to be the first on my list of 3DS games.
I was blown away. The graphics are incredible for a handheld console, and the gameplay is the best Lego gameplay I have come across. Having loved the Lego: Star Wars games, I started to become a bit disenchanted by their later releases, especially Harry Potter, which relied far too heavily on puzzles and long, sprawling levels.
Lego PotC keeps the puzzle-solving to a minimum, while having more combat, so you will never get bored. It includes 16 levels, 4 from each film. If you haven't seen the films, I doubt you will follow the story of the games, as the Lego videos are always for fun and obviously don't have much of a plot.
The game takes about 15 hours to complete and collect all the hidden objects. For the visuals alone, I would recommend this game, but when you add the hilarious Lego moments, fun gameplay and replay value, I would say it is a must.
Also, Jack Sparrow's in-game walk is hilarious. Worth the price tag alone.
