This is a great game and as you can see, I felt there were no significant concerns. I love this game (and this website; I believe this website is a great tool, plus, this is my first review), although it is a little difficult. I usually turn the blood off, as my parents don't like it, so that takes the violence down a step. Another step I like to take is be non-lethal, because in the game, Snake (the protagonist) has a tranquilizer pistol (but unfortunately, that isn't so realistic in wartime). He can obtain flashbang/stun grenades (which knock out his enemies), use CQC---a usually non-lethal, hand-to-hand fighting style---or just sneak by the enemy without taking anyone out. The game suggests sneaking, as the enemy AI (artificial intelligence) is built around looking for Snake. Even when a player reaches the 'Bosses' in the game, they can be defeated non-lethally, which gives the player a bonus or reward. I think that would definitely still keep the violence down, since that player would like that they got something for a challenge. Unfortunately, I've come to the hard part of my review, where I have to point out the bad part (I like being honest, but hate pointing out errors or bad things) about the boss fights: Some people may find that hard (I find it challenging) to do so, which could go back up a step. The player could quit trying non-lethal and get frustrated. Aside from that, the sexual content is only suggestive; no one ever is absolutely bare. EVA, the woman who is suggestive, is only ever in her bathing suit at the most, and in addition, children can skip the cutscenes by pressing the exit button (X). The interrogation scene can also be skipped (although i haven't played in a while, so i am a bit unsure about the first part of it) with the same method of pressing X, while the start button may work also. I wanted to point out in the review made by this website that (I believe, I am unsure) burning off leeches with a flame or cigar is not the safest thing. In the military though, one such as Snake could be desperate to survive, but still: it isn't a safe message, but it could, in one's mind, counter the bad cigar element. But this game is very historically accurate, making it quite obvious where the seams of fact vs. fiction are, and is also accurate in many other manners, such as the weapons, animals and environment. This game gets 10/10, 5 stars, pretty much the max. from me for rating for the good things about it. It's fun, historical, realistic (or not), the innapropriate things aren't too worrysome, and it has great gameplay. I believe this game would be appropriate for a 15 year-old, possibly a 14 or 13 year-old who is very mature, and would not be one to To my knowledge, my review was not bias, and I really hope i did not have too many parentheses.
