I got hold of LEGO Star Wars for the PC and have been playing it for the past few days during breaks and after class. I was unsure whether to play through Episode III since it would obviously contain spoilers for the movie. I went ahead though and have completed the story mode and am now going through the Freeplay mode to try and unlock all of the bonuses, (such as extra characters.) It is a great, simple little game that is fun to play, (even if there are a few frustrating sections, such as the jumping around at the end of the last level.) In between all the usual lightsabering levels are the occasional vehicle levels which add a bit of 'on-rails' action for a change of pace. I would probably give an 8 overall, with a high recommendation to try it. Marks are only lost for being a little short, (but the replay value is quite high,) and a bit of repetitiveness creeping in. Hey, you get to be Samuel L Jackson in LEGO form. It has to be good.
Having played it I am looking forward to May 19th even more. If the movie is anything like the game, this is going to be a high action Star Wars film, which has always been the best part of the other films. Lets face it, star fighters and lightsabers rock. Trade blockades don't.
