When it comes to singing games, I don’t mess around. I go all out, because my pipes beg to be strained. My voice longs to become hoarse and weak, and all for the sake of belting out some of my favorite tunes. And can you blame me? These days you can get virtually any song you want on most of the karaoke alternatives for gaming consoles. Many turn to Rock Band and the latest iterations of Guitar Hero for their singing fix, including myself. Still, I’ve rather enjoyed the simple pleasures I can get from Lips, Microsoft’s exclusive karaoke title. While the original game built a sturdy foundation on which the franchise could grow, I can’t exactly heap praise upon its pseudosequel Lips: Number One Hits. While it manages to hit some glorious high notes, its timbre is still a bit warbly — and that’s something that worries me about the future of the series.
