Love your war brutal and realistic? 2009 is your year. Two open-world soldier simulations are coming, both of them with serious heritage.
The first is ArmA 2, a sequel built by the military nuts that created the greatest soldier sim ever in Operation Flashpoint, Bohemia Interactive. They're obsessive on detail but light on polish, as their last game, the first Armed Assault, showed. Fixing this should be their first priority.
The second sim is Operation Flashpoint 2. A new team, working to produce a game with the same relentless detail, but with a modern level of style.
