Let's imagine a distant binary system in which both stars are equal in mass, therefore both stars have warp points (or jump points, your choice). Both stars have an inhabitable planet, each with a star-faring race. The halves of the system are roughly equal in usable resources. The number of WPs is equal, and the races are about at the same point in their technologies. Oh, and they hate each other. The two sets of warp lines outside the system do not converge anywhere but in the home system. The two stars are fairly far apart most of the time, but they come within one light week of each other about every 100 Earth years. Get ready, get set, go!
