I'm trying to decide on a singing/karaoke game and I'm not sure whether to go with Lips or Singstar, as I own both a 360 and a PS3. I was wondering what types of gameplay differences there were between the two games in regards to single player depth and party play, how large the DLC libraries are, and what kind of compatibility between other games the microphones have/accept.
I have a Rock Band 1 microphone, and my entire collection of GH/RB is on 360, so I'm leaning towards Lips for that reason, though I'm not sure if Lips accepts the RB1 mike. Lips lets you import your own music which I didn't know until I read that question, which is one of the biggest appeals for me. Does Singstar offer the same?
