you can add AI aircraft? that would be amazing! how do i do that bud? do i need an addon pack? i have the basic game, i want as much AI and scenery as poss, any advice?

Take my advice.depending on your system be carefull how much traffic you add in your sim cause it can bog it down where its not fit to run.i would down load TTOOLS and  the afcad for fs2004 and read the information that comes with them and learn to use them.then add traffic in a little at a time and test it out.that way you wont run into a problem you cant fix.but even if you use the project ai addon traffic you will still have to learn to use afcad and add in extra parking for the traffic or the aircraft will disapear at the end of the runway cause there is no where to park and real as it gets wont be so real any more.learn to add the traffic in yourself and dont use the project ai installer.learn how to use those two wonderfull programs and you will be glad you did in the long run.
