Arkham City is the new title in the Batman series. (The first was Batman: Arkham Asylum.) The goal of the Batman creators was to allow the user to be Batman the detective, Batman the hero, Batman the avenger so you have to look for clues to figure out what the bad guys are about, use stealth to sneak around to save the weak and when push to shove, use your fists, cape and cleaver bat tools to really kick some butt. Of course true Batman fans know that he never kills anyone although some serious broken bones may be in the offering. Completely appropriate for ages 10 and up if you are looking for holiday gifts. I think the Wal Mart version includes the entire first game (still worth your $50) as a bonus while the Game Stop version includes an add-in that allows you to play some aspects as Cat Woman.
