All Star Wars games are mostly on a great/horrible basis. Clone Wars barely makes it in some respects, while blows past it in others.
Gameplay: While some say it is on the short side, I say it is just right. With three difficulty levels and 16 levels to complete, along with three bonus objectives for each of the levels, it can take along time to complete. On the other hand, the framerate can be very bad at some points. However, if you aren't a person who really pays attention to that stuff, you won't notice.
Replay Value: With 4 modes of multi-player and multiple maps, as well as unlockable features, this game is not one to put back on the shelf and forget about. There are four different modes, each one of them a blast. First, there is your regular duel (ie Free For All). You can have teams, making it 1 vs. 1, 1 vs. 2 1 vs. 3, or 2 vs. 2. It's a good addition to this game.
Academy is sort of like Endurance on Rogue Leader. Up to four people can play and take on wave after wave, taking the role of either a Jedi on foot or in a tank.
Conquest is by far the best one. Conquest is a sort of strategy game putting you as one of the units on the field. Gain outposts and AI's to destroy your opponent. Can be in teams of 2.
The last one is called Control Zone and it is another mode that is normal in this type of game. You have to take control of a zone and keep the other players out of it.
Graphics: Doesn't really need much explaining: GOOD!! Not as good as Rogue Leader, for instance, but very well. The only thing that slows it down is the framerate is not very good
Well Tom, I think that is all. It is possible to beat this game in a rental period, great multi-player only adds to the fun.
I highly recommend it and i think you should get this game!
