I am not a gamer at all, but my husband got addicted to this game and insisted I try it. It is really a fun game! The programmers who made it must be tops in their field because there are very few glitches or bugs and the game-play is very intuitive. The detail is just amazing - from stars in the sky to footprints on the ground, they haven't left out any little thing. You really become part of this imaginary world.Even though a large part of this game involves killing members of the other faction as well as various other computer-generated beasts, this is not a mean-spirited game. It's difficult to be successful unless you team up with others and cooperate. I have seen a lot of very altruistic, helpful, and generous behavior from other players. There are always a few dorks around, too, of course, but for the most part this game seems to bring out the chivalry in its players. I'd recommend this game for age 13 and up.
