Got to agree with Joe. Look at Americas Army, a "game" fully funded by the army (read government). To me that's just sinister. Motives? Obviously recruitment.
"America's Army Government Applications office was quietly opened in January in Cary, North Carolina, with a team of 15 video-game creators, simulation specialists and ex-Army personnel. Many of the studio's employees come from local video-game companies like Interactive Magic, Timeline, Vertis, SouthPeak Interactive, Vicious Cycle Software and Red Storm Entertainment."http://games.filefront.com/4;/Americas%20Army/
