Not often enough are games made with 'fun' in mind. And this one is. There are no levels which are a chore. Each one has its charm and humour, as well as replaybility.
The main focus of the game is to play through the original trilogy. Just about every character you can think of is playable. You have the main set, although the number of Jedi has been cut dramatically to just four in this game. Minor characters such as Greedo and Wedge are completely playable. Several have their own personalitys, like Han will ride creatures backwards, and Lando will hold on to Princess Leia's hand when attacking her. If you like to experiement in your games, then this is the one for you.
Completing a level with the usual cast, Luke, Han, Leia, C3PO, R2D2 and Chewie is one thing, but replaying the same level with a team of Darth Vader, Ben, Boba Fett and Lando is another.
It is a core platforming game but there is plenty of puzzles which will tax your brain and many easter eggs which will make you laugh out loud, for example a couple of Stormtroopers taking a hot-tub break together, and nobody recognising Chewbacca because he has half a Stormtrooper helmet on his head.
Lego Star Wars II: The Original Trilogy is well worth the buy, as it will change and influence your future views on gaming. You will never have as much fun when playing a videogame!
