Landmark presentation must balance information density and clarity

What it is

Landmark map legibility decides which places, routes, entrances, hazards, and objectives appear on a minimap or full map and with what graphics, labels, and hierarchy. Too few landmarks leave routes without reference; too many bury important places in symbols. The aim is location and memory support, not copying all world data into a map.

Why it happens

Players use salient, stable, nameable places to chunk routes and align map model with world view. Clear landmarks reduce the search for where they are and where to go. Each mark also occupies discrimination space and adds classification burden. At densities where symbols occlude, look alike, or labels overlap, more information becomes less usable because task-relevant cues cannot be found quickly.

Where it stops holding

Exploration games may intentionally delay marking to promote environmental learning, while strategy or cooperative games can need richer shared information. One fixed density cannot serve newcomers and experts. The question is not whether fewer icons are better, but whether visible landmarks match task, scale, discovery, and intent with filtering and search available.

Applying it

• Choose default landmarks by function, stability, and decision frequency, using discriminable form, text, and grouping and controlling labels and detail at zoom levels.
• Support filtering, search, custom marks, and task-relevant temporary emphasis, so every category does not compete at equal strength.
• Verification: ask players to locate and retell routes on maps with distractor marks. Measure finding time, misclicks, and landmark-location memory to adjust category and density.
