Singularity is an everything clone. It reminds me of Darksiders in that respect. It took the good bits of every FPS, the way Darksiders took the good bits of 3rd-person action games. It does it well, though, and I'm also enjoying it. The storyline is particularly entertaining, and I like the variety of ways that its exposed to you. The "Loose Change" styled video that you get from the briefcase was pretty awesome.
