9: Tom Clancy’s Ghost Recon
Operation Flashpoint’s little brother. Ghost Recon, the first game in what has now become a long running franchise, was a variation on the realistic, close quarters tactical combat focused Rainbow Six games, created by the same developer, Red Storm. Ghost Recon instead focused on large, outdoor levels with slow, stealthy approaches and team tactics. However the simulation aspect of the title wasn’t quite as prominent as in OFP.
