Gamespot says that this version of Star Wars Episode III is the best of them all, and for good reason.
Game Play: Simple but good. The entire game is just a side scroller. You can walk to the left, to the right, or up and down. You play as either Anakin or Obi-Wan and you chop up droids. Every three or four levels, you fight a boss. You block the bosses attacks, then you attack. It sounds simple, but in reality it's really fun.
Also, only in the DS version, are space battles. They are added into the storyline every now and then. But the main part of the space battles, is the multiplayer. You duke it out with up to three of your friends in space or above ground on the planet surface. It's very fun but each of your friends need to have a copy of the game each.
Graphics: Sweet. The graphics of the main part of the game are clear and everything looks right. The graphics look like they did from the Clone Wars cartoon series. The space battles are like nothing I've ever seen before. You fly around in complete 3D and shoot at enemies and dodge obstacles. The graphics are just awesome.
Sound: Yet another Star Wars game, yet another perfect soundtrack. With the new ability to produce excellent quality sound through the DS speakers, unlike the GBA, you get stunning sound. John Williams score, blasters, lightsabers, everything is here and totally complete. It really gets you in the mood for slicing up droids.
Value: While I may know a lot of people who don't like this game, I know a lot more who do. For a DS game I was very surprised. I'm going to have to soon realise that DS game normally are better then I expect them to be.
Rent or Buy: Buy. With such a good game why would you want to rent it. You'll just want to play ti all the time. That and I still don't know where you can rent DS games anyway.
