I am satisfied with everything in UK charts, however I am still not sure why an awful game (Dance on Broadway) is nearing first place. To be honest I think the game should be removed completely due to its lack of every main concept of a game.
Super Mario Galaxy 2 can easily acheive 5m in sales (overall, worldwide) due to its consistency in each regional chart across the world. However remarkably both Super Mario Galaxy and 2 have not topped the UK charts but have stayed in the top ten for several weeks.
