Unfortunately i'm prepared to bet hard cash that LucasArts own the concept too. So a game in even vaguely the same style would have to pay money to them. Copyright my frfiends.
I lost a DS the other day, i removed fighter from the game, but of course the rebels always start with some, and sure enough, first run they made, they destroyed my lovely weapon of mass destruction.
When playing against the ai there's no point, it moves as much as it can straight away. Also i've been playing as the rebels recently and the Imperial ai doesn't seem to attack either.
