The only reason I set the age limit this high is because of the difficult strategy required to make it far in this game. It is like playing an incredibly complex and detailed game of chess, in which the board, pieces, and rules are constantly changing. Its an incredible game though, really entertaining. I love the Fire Emblem games anyway, but the concept of adding the race of people who can change briefly into animals is very interesting.
This game is intended for older kids in difficulty level and story line, but there's little in this to make it inappropriate. No language, certainly; everything is very old english sounding and proper. However, there is death; you are trying to kill the enemy using your little army before they kill you, its like a board game of war. No blood, attacks not graphic, but your characters fall in battle (rather than dying, they get injured and you can't use them anymore) but enemy characters do die.
