Mario Super Sluggers (Wii)
Namco Bandai
August 25

Mario Super Sluggers, launching Aug. 25 for the Wii console, stars the ever-lovable Mario and his crew of friends. It builds on the social-gaming fun and movements people learned in Wii Sports and turns them into a full-fledged baseball game that can be played by every member of the household. Players make a throwing motion with the Wii Remote controller to pitch the baseball and make a swinging motion to swing at the pitch. The game boasts more than 30 playable Nintendo characters and all the madness of a Mario sports game. Just like Mario Kart Wii, it bridges the gap between experienced players and those new to the Wii console, with fun challenges and beautiful graphics.

Wario Land: Shake It! (Wii)
Nintendo
September 29

Wario Land: Shake It!, a classic side-scroller for the Wii console launching Sept. 29, stars Wario, the smelly, bad-mannered alter ego of Mario. With the Wii Remote controller turned sideways like an old-school controller, veterans and newcomers alike can run, jump and smash their way through hectic side-scrolling stages. Players shake the Wii Remote to help Wario take down his enemies, empty bags of treasure or cause earthquakes. Best of all, there are numerous stages each offering multiple missions to keep players coming back again and again to unlock everything, collect more coins or just improve their best times.

Mystery Case Files: MillionHeir (NDS)
Big Fish Games
September 8

Mystery Case Files: MillionHeir, launching Sept. 8, uses the unique Nintendo DS interface to expand upon the seek-and-solve game play of the popular series from Big Fish Games. Players seek out cleverly hidden items in a multitude of painted scenes. Players progress through an interactive detective story investigating a cast of characters and uncovering new evidence to find the rightful heir to a million-dollar fortune. This new portable installment is available only for Nintendo DS. With interactive logic puzzles that use both the touch-screen interface and built-in microphone and include the first ever multiplayer mode for a Mystery Case Files game, Mystery Case Files: MillionHeir presents a new generation of seek-and-solve games for casual gamers and franchise fans.

Kirby Super Star Ultra (NDS)
Nintendo
