Its not exactly a bad game, no matter what people say.
1. campaighn is long and good and you get a lightsaber and stuff when you complete it.
2. its not just empire v rebels, it can be droids v empire, rebels v republic etc.
3. weapons and variety is alright.
4. Includes jedi combat mode which is very fun.
this game a a truckload of downsides though:
1. Graphics (especially heavy imps and heavy rebs) are excruciatingly terrible.
2. you can only go to 4 places in instant action, despite that (if lucasarts wasnt lazy enough) we could have coruscant, geonosis, mustafar, yavin 4 and all the other places in story mode.
3. the instant action battles are dull and boring, as there can only be 2 teams and the battlefield is massive so theres to much room!
However, this game, despite its downsides is only a first for the ds and i didnt expect it to be much. it is worth a play but beware of these downsides!
