Word on the streets and web was about this game that mimics Fallujah battle, but it was never released because of upset families.
It was not released due to the publisher backing out. They've been hoping for a new publisher but nobody decided to pick it up yet.
Anyhow, out of the recently released games, Prototype has been popular but I haven't personally played it. Most of my recent gaming has been with a couple of retro games and XBLA games on the 360. I started playing through Halo 3 again last week.
