A fun game, but too easy and too short.
You play through each prequal movie, which is divided into a few chapters. One of which is an on-rail ship shooter, and not that fun. The rest of them are action/platform levels. There are also many puzzle in these stages that are pretty easy. The game also has drop-in, drop-out co-op.
In conclusion, Lego Star Wars: The Video Game is a good game. I reccomend it if you are looking for something that isn't hard.
