120 real units. By that you mean plotting 120 paths simultaneously using a common flow algorithm used by internet routers which is more than fast enough and reasonably easy to speed up or truncate. The tricky part is on assigning nodes on a contiguous map or reducing number of nodes. (Or expanding node resolution on demand.) Of course many games of the time side stepped it by using greedy truncated pathing instead. Easy, dirty, mediocre results.
