For what it's worth, team-based FPS games use a similar style of map design. For instance, in Counterstrike, most popular maps have a middle area of contention. This area can be used to reach each of the objectives. Teams have the option to attack the objectives directly, or take control of mid and decide where to go. There are almost always multiple paths between each of the contention areas, and the player spawns, so it's often difficult to predict what enemies will do because they have so many options. These maps are much smaller than interesting FPS maps I remember from my childhood, but the principle is the same.
