Americas Army's gameplay is good but...
If you're patient enough to wait for the loading times, the training missions were quite useless. Since sometimes when you're playing online with other players, theres bound to be one person who thinks he's rambo and runs guns everybody. The training missions did get you acquainted with the controls though.
The sound in my opinion was pretty good, guns were loud and explosions were pretty good becuase I cranked up the volume.
Graphics, if turn the resolution up very high expect very good graphics. But obviously , for slower computers if you put it on 800 x 600 res or 640 x 480 res don't expect top notch graphics.
Overall I do recommend this game to people who have faster computers but for me I'll never play this game because I'm not patient enough for loading times.
