It's a movie tie-in. That's all I need to say.

Pirates 3 for the Wii is too rushed, the controls are too repeatative, no free roam, it's too short and it has no upgrades.
If you like your games long and solid, do not even stop to consider Pirates 3 for the reasons above. You start the game, you feel like, yeah, this seems pretty good, then you realise you have played it for an hour and are close to the half-way mark.
Before I bought Pirates 3 for the Wii, I had played it on XBOX 360, it is still short on the 360, but it is much better, each character has their own finishing moves that can be quite entertaining.
For the Wii it does have some replay value but not enough, but then, what did you expect from a short game. The controls leave your wrist sore from constantly waving the Wii-mote.
Still this game is pretty good while it lasts, and a few hours of fun can be had. I found the most entertaining part of the game was Texas Hold 'em Poker and Pirate Dice which can be both be found in the levels.
Pirates 3 for Wii rhymes.
