In the beginning, when Americas Army was first on the drawing board, the army likely wanted to use AA for propaganda and as a recruiting tool. They also wanted to train soldiers with it because of its realistic environment and weapons etc...
However, I think it ended up differently then what they originally wanted it too be. Instead it became a fun, realistic first-person shooter, JUST LIKE ANY OTHER GAME!! But, in the end, how people view the game, either as a recruiting tool or just a game, is up too the perspective of the person writing about it. I personally like this game and I see where the propaganda supporters are coming from. (Having a few in my family.) However, I dont support their views. I think it is just a FUN GAME! and we should LEAVE it as a fun game.
