Just pure fun.
While you're playing the game then there's just something about it that says that is entertaining but anyway, let's go on.
Graphics: 8/10
The graphics for this game were pretty decent considering that it came out in 2005, as you can usually tell that the guy with ginger hair and a beard is Obi-Wan and it stays solid all-round.
Gameplay: 9/10
This game, as I said earlier is probably more for younger kids but mostly people of all ages will enjoy this as it feels very rewarding as you finish each mission and get all the collectibles. Lego star wars also has a lot of things that you need to collect in different stages, such as minikits and the Lego studs, (Lego currency,) The studs are needed to buy new characters to unlock certain areas or cheats. In each level there is a stud meter which you need to fill. Do that 17 times and you get a very special reward.
Sound: 10/10
Basically the excellent star wars music. What more is there to say?
Bonus content: 7/10
This game has a fair bit of it, and one particular piece surprised me. To people who have played the game: the one in the door next to episode 3.
Value: 9/10
This game is probably worth about $10-$15 considering it is 2011 and the complete saga is out.
Humor: 10/10
Seeing these guys that you are all familiar with in lego, losing their heads, smacking to pieces, (no blood,) and grunting is enough for you to roll over laughing!
Overall: 55/60=9/10
This game is excellent but the complete saga is out which has all 6 movies plus loads of bonus missions, characters, extras and loads more. So just go for the complete saga as it has this but it's still cheaper.
