Every now and then seemingly every development team on Earth will become obsessed by something glittery. They'll crowd round it and make hubbub noises, before dashing back to their design coops to create their vision. For a slice of the last decade the obsession was rudimentary NPC squad control. Every game was at it whether it needed it (Brothers in Arms, SWAT 4, Republic Commando) or not (Half-Life 2, Medal of Honor: Pacific Assault). Freedom Fighters, however, did it best.
