Weird idea, great game. If only all games were like this!
No matter what age you are, there's something fun for all in this game. There is the simple Drop In and Drop Out multiplayer gameplay, which helps a lot. You can play as any character from the 4, 5, and 6 movies, even Santa Claus, though I'm still trying to unlock him. All the characters from the movie have been faithfully re-created in Lego versions, and each of the main characters has a special ability, like Chewbacca being able to pull of Lego people's arms, or Leia being able to slap other characters. There is plenty to keep you returning, from new vehicles you can build by collecting special mini-kit pieces, and the gameplay is just so simple, it's fun. Another great aspect, is designing your own Lego man, using pieces of other Lego men you've defeated in levels. The levels are not completely made of Lego, though things you can interact with are Lego pieces. The missions are basically get from one end of the level to the other, though there are some side missions, like the Bounty Hunter missions, which help you get gold bricks, another new additions to the games.
There is basically no bad stuff about Lego Star Wars 2, though people who are for more serious games, you don't have to play it, so don't bash it.
Lego Star Wars 2 is the pick of the crop in terms of video games.
