Okay, the only ones of most of these games I've played is Gears of War and I don't really think it rises above the level of the general quality of the original movies on the Sci-Fi Channel. Like the one that is on right now, I am Omega. Its monsters even look like thin Locusts and I think it is based on Richard Matheson's I am Legend.
I have also played Bioshock, and it was quite a bit deeper.
I played the first two Halo games. I thought they were pretty cool although storywise they were typical space adventure fare. I have heard that the story in 3 wasn't that awesome. Ie. That it didn't really add much to what was already known about Master Chief or Cortana from the first two games and that it didn't add that much about the Forerunners either.
And Alan Wake just looks like horror films I have already seen before with action elements from Max Payne.
