My fondest memories of the original Star Wars films were the starfighter dogfights. The first time you see the assault run on the Death Star, or the ill-fated attack on the second before it was finished, it's really cool to watch a bunch of fighter craft flying around, blowing the heck out of each other. Every once in a while, you can get the same sense of scale and calamity in a game - usually of the real-time strategy variety.
