I won't say anything that has already been said about the quality of the game or its lack of "next-gen-ness" and online-play.
I will say that when I play a Star Wars game, I expect to do some cool force stuff and kick some butt with a lightsaber. Granted, this is the original trilogy and there simply weren't many actual Jedi in the films, the levels where you play a force-wielding character, at least in Story mode, are few and far between. You will have to play the game in free mode with a Jedi/Sith if you want to have all the fun you can.
The force powers themselves are strictly limited. There is no force pull, only push, some items can only be built using the force, and light-side Jedi can really only use confusion on the enemies. Lightsaber combat also sucks, it is hard to deflect blaster beams efficiently and the lack of any good combos often left me playing a blaster-equipped character and switching to Luke or Obi-Wan only perform force-only environment interactions.
Better Jedi play would have made this game a 9 or 9.5 for me. Because honestly, thats what should make this game worthy of the name Lego Star Wars.
I know this game is geared towards ease of play and simple enjoyability, but I found Jedi Outcast and Jedi Academy to be equally as simple with a much much much better representation of what being a Jedi is like. Hopefully LucasArts won't be stupid and kill that series, it could be awesome on the 360.
If you never played the first game, play it. Even if it is based on the prequels. They got everything right about this game. Too bad its short. Do not rent this game. Instead, buy it. But, if you have an xbox 360, then buy the 360 version of this game to see the full extent of its graphics.
At first glance you seem to think that this game is directed just to kids but after a little one on one with the game it offers alot of things for all ages. with some pretty complex puzzle solving to hilarious cut scenes. this is a great game for the whole family.
