Batman leads a league of sequels headed for video games this year.

The Caped Crusader's "Batman: Arkham City," due this fall for PS3, Xbox 360 and PCs, joins follow-ups in the "Zelda," "Gears of War" and "Mass Effect" franchises.

"2011 looks huge for new releases, maybe even fuller than 2010," says Leigh Alexander of industry trade site Gamasutra.com. "Many beloved franchises are getting sequels their fans have been waiting for for a long time."

Despite last year's high-profile hit follow-ups such as "Call of Duty: Black Ops," "Halo Reach" and "New . ," total industry sales were down 6 percent, at $18.6 billion, according to market tracking firm The NPD Group.

While publishers will again lean heavily on sequels to proven titles, some surprises are in the pipeline. Due Feb. 22 is an over-the-top, first-person sci-fi shooter, "Bulletstorm" ($60, PS3, Xbox 360 and PCs; ages 17-up). "L.A. Noire" (PS3 and Xbox 360, no price or rating), a detective thriller from Rockstar, developers of "," arrives May 17.

"Sequels are not necessarily a bad thing, but if there weren't games like "L.A. Noire" coming, it would be much more concerning," says Brian Crecente of game-news site Kotaku.com. "You look at the big titles, almost every one that people are talking about has numbers after the title."

Sequels do improve on past games. Already out, "LittleBigPlanet 2" ($60, all ages, for PS3) adds environments and lets players design their own games. "Gears of War 3," due this fall for Xbox 360, has female squad member characters and a five-player multiplayer mode. "The Legend of Zelda: Skyward Sword," due later this year for Wii, heightens the sword-wielding action.
