The gameplay of UltraStar Deluxe is similar to that of the commercial product
SingStar™ by Sony Computer Entertainment, which is exclusivly available for
Playstation®. However UltraStar Deluxe allows to create own songs and as well
differs from other karaoke programs in further aspects. It allows you to play
with up to 12 players and sing along to your favorite songs. You do not even
have to buy expensive DVDs with not so many songs you really like, instead
just buy DRM free audio files, use your album/cd music you already own and
so on - You'll notice that this is way cheaper because you won't ever be
charged twice for a song you already bought in the past.
