I've been doing other things though. I like to pick off the limo driver as he rounds the corner, then the limo agent, then Governor Connally, his wife, the First Lady, then finally JFK. The car behind it carries the Vice President, his wife, a senator, and a bunch of other various people.
They all sit there and look around clueless, and they all die one by one. I start getting less picky about who dies next. Even a photographer gets popped. The simulation obviously deducts massive amounts of points from my "score".
You can download it here for free. I think this simulation is how the Kennedy assassination should be taught in schools. Maybe I'm just sick in the head, but it's a lotta fun!
