As I once read about this game, skip the easy "Agent" level. The real fun in this game lies in sneaking around the stealth part. Unlike other First Person Shooters (FPS) this game isn't about mowing down everyone in sight. Instead, it's a gorgeous game (alas, with the traditionally poor Rare frame-rate especially in multiplayer) where you have to think about every single move you make. Along with Majora's Mask, its the reason to get an Expansion Pak. (if you don't have one and want this game, I strongly suggest you get one either by itself or with another great game, Donkey Kong 64 which is now a steal at .... If the expansion pak is ... by itself, you do the math.) The controls are superb, and it's very easy to get the swing of things. However, it is very bloody and the deaths are realistic. Parents should let kids under sixteen rent it, then watch them play it to make sure it's ok. Other than the blood, there is some mild swearing at about the PG-13 level, it's nothing too bad. Multiplayer is fantastic, with 'Capture the Briefcase' the best scenario.
