I play this game on a regular basis . yes - the interface be clunky . I get use to it ... fast . yes - the Tutorial be buggy . the Title Update on Dec. 7 2010 by download on XBOX live fix that . I love the tutorial now and how you can learn the latin dance move . it work . yes - you get sign out of play . Make sure the light be on in the room you be play in and put the dog in another room . I have master the skill of sign back in . ugh . hopefully more title update for the Zumba fan that do not return the game ! I do a big ol review of this on my blog when it be first release , and luckily the title update have improve on one of my biggest complaint ... that tutorial . this be not the best game a development company have make for XBOX Kinect . we also have other Kinect game and love to play they . fyi - Majesco really do not have stellar title in general , but this be the best zumba game - yeah , its the only zumba game ... LOL ! however , this may even be the best Majesco game . hahaha , Congratulations ! Zumba fanatic like I will deal with the glitch , help debug the game by complain online about feedback ... and have fun with the game regardless . it be possible , and I will say I work out way harder with this than with Dance Central , but Dance Central be more fun to play . the Zumba title have about 30 song with dance routine . the music be all good , it be the regular zumba stuff that Instructors use , it be hard to get this music on a cd for yourself . the music be addicting ! dvd be also a good choice for those who want to workout at home . grab a friend and jump into a Zumba class be the best ! it be not for everyone , but I have lose 50 lb since start Zumba 10 month ago . I do not know what the heck I be do but it be so fun ! I refer to Zumba as the `` gateway drug to fitness '' for people who resist regular excercise . I now enjoy other activity and love my Zumba . my thought be , this game might help some people who be too shy to get to class . the game be playable , Zumba be remarkable .
