Any of guys ever play the video game from around 5 years ago called "JFK:ReLoaded"? Your the sniper in the TSBD or you can be on the grassy knoll or at the Cal-Tex building. The object is to match LHO's shooting but i just blast everyone.

Pretty small game with primitive graphics but it's addictive.

JFK's family complained about it so the software company stopped selling it and i think it's freeware now. Check it out.
