Most songs are either crossovers from other Bemani games, and Japanese pop and rock. Some mixes also contain covers of popular North American songs. Songs are primarily in-house original compositions, covers of popular Japanese or English songs or edited master tracks licensed from the artists. Most songs are pop and rock in style, although there are often a wide variety of musical genres available. Reception The arcade game was popular and played in arcades throughout Asia. The PlayStation port of DrumMania received a positive review from Dave Zdyrko of IGN in 2000. He said that, while the game lacks realism and that it was "nothing at all like playing real drums," it "provides for one of the most addictive and enjoyable videogame experiences since Tetris was first unearthed." Legacy and impact It is considered one of the most influential video games of all time, for having laid the foundations for popular guitar-based rhythm games, such as the Guitar Hero series. GuitarFreaks is believed to have inspired Namco's similar rhythm game Guitar Jam, released later in April 1999. GuitarFreaks and DrumMania inspired the development of popular North American console game franchises Guitar Hero and Rock Band. The Huangs raised $1.75 million for the effort, despite being turned down by some investors who "thought [the idea] was too weird". In 2008, Konami sued Rock Band developer Harmonix for allegedly violating three patents for its drum and guitar based music games. The lawsuit was eventually settled in 2010 and its claims dismissed. Konami also partnered up with Activision for post-2007 Guitar Hero games to comply with Konami's drum and guitar games patents, and eventually in 2009, the two, along with Raw Thrills, released Guitar Hero Arcade in North America. Releases In Asia, outside of Japan, DrumMania releases from 1st to 10thMix are known as PercussionFreaks. The PlayStation 2 port of GuitarFreaks 4thMix &
