Singstar for Playstation 2  

So we have a Playstation 2 for the kids that they play every now and again, my husband and I aren't much into playing video games but with winter coming we were thinking about looking for something that we can all enjoy doing during the winter since we aren't going to be going out much. We already have board games that we do and my daughter and I both like to sing (as amateurs) so I asked for the Singstar game from my husband for Christmas that way we can all enjoy it. I am not sure what all I need for it thought since I am not a gamer and was wondering if anyone had this and could help me out.
I know you need the microphones but do I need different microphone per game or will the two microphones work for any game I choose whether it be 80's, country etc. I know I will have to get the game of my choice but do I need anything else to get this working? Thank for any help.
