I posted my review of this game (hasn't shown up yet), but I also mentioned that my two 6yo boys love the game. But in my review, I also mention that I got hooked on it as well. I've always loved the Star Wars movies and this game is very true each episodes plots. The Lego characters are amazing and have some pretty humorous spots in the episode trailers. This game is enjoyable for kids and adults...no question about it:-)
I played this game at a friends house got addicted instantly. It's like Mario Bros., yeah it's for kids but you play it cause it's great fun. Has some jokes in game that most kids won't get and most of the humor is tounge in cheek because how serious can you be with a game that is made entirely of lego's. It's one of those rare games that doesn't mess up a potentially good thing.
I would say it depends on what the adult is looking for in a game. You don't really die in this game. When you run out of life hearts, you blow up into little pieces, but you come together right away with a full compliment of life at the exact point you died. The game has objectives that need to be met to move forward, and there are some puzzles mixed throughout. It is well made and quite a bit of fun with many extras to give the game some extra play life. Adults that normally don't like button masher games and don't mind the Star Wars theme will appreciate it the most. Adults that live for such action games as Unreal Tournament or Call of Duty may not be as pleased, yet even they might be surprised with if they give it a chance. It uses both the wii remote and the nunchuk, so if you want to play with 2 players you need two of each.
