A very solid Batman game! They did so much right here - the Joker storyline is solid, with frequent taunting from him over the PA as you go, the gadgets feel great to use and really make you feel like Batman, the combat is simple but deep enough to be fun, the stealth mechanics work well, and the gameplay is streamlined so that you spend most of your time doing Batman stuff rather than some of the busywork you get in other games (scrounging for health pickups, poring over maps, managing inventories, etc).
