Singstar Queen is a karoake game for the Play Station 2. The songs in it are basically all of Queen's Greatest Hits. Singstar is unlike the average video game, because it appeals to basically anyone. Middle aged women will probably enjoy this game more than teenage males, but that is no harm in itself.
The idea of the game is very simple: scroll through a list of Queen songs and then after choosing one pick one of the different modes. There is an option for single player, but this is definitely a game for two or more people. Get a few people over and possibly a few alchohol beverages and you will have a brilliant time singing "We are the Champions" and mimicing the late Freddie Mercury's best stage moves.
You are given a rating about your singing, but it doesn't seem to be very accurate, as anyone who saw me given a rating Pavorotti himself would be proud of will testify. The volume seems to be the main factor on whether the game judges you as a good singer or not.
One problem I had with this game is that unlike the other "Singstars" it only features Queen songs. Even though the nature of Queen's songs is that the majority will like and know them, some variety would be nice.
