Are real terrain features represented 1:1 on the table?
No. A single real-world terrain feature can be presented by more than one terrain feature on the table (e.g. woods) or several real-world features can be grouped together as one on the table (e.g. buildings) . Each wood feature in Crossfire represents the amount of terrain it takes to block sight. This may take some re-thinking of your concept of terrain. If you want blocking terrain on your table then you should use many small features – representing a dense wood. A few large features represents a relatively open wood. But remember that even the gaps between woods features are still part of the real world wood; they are simulated as open space because they are relatively open compared to other areas.
