There are, of course, limits to how much intelligence gathering you can achieve by firsthand observation. A network of spies will extend your vision, particularly as you learn to interpret the information they bring you.

Try to make friends with people at or near the source of information on your rival; one well-placed friend will yield far more than will a handful of paid spies.
