Seriously underrated, one of the best Star Wars games ever. Not just a typical hack and slash game Star Wars has become.
Many of the levels are simply inspired, one of my favourites was Theed, whereby you had to navigate through the garden mazes whilst avoiding the big old tank patrolling. There was also alot more subtlety and freedom in the game, you could either try to complete a level by going all out and killing, or minimalise the slaughter and attempt mini missions which rewarded you with useful items, often if you completed levels without killing unnecessarily, you would get some form of reward item which could be used later on in the game to complete a difficult mission.
10/10 even now, 10 years after the release.
