One of my design goals in Hellmouth is to emphasize knowledge and perception as alternative playstyles by making them as game-changing as combat attributes are in most games. Consequently, there will typically be a lot of information about a situation available to the player at any one time. Games that provide a lot of information can be very intimidating, and unfortunately one of my favorite games is well-known for failing to usefully communicate its rich complexity.
One of the ways that I’ll get a handle on information overload is by providing reasonable defaults but allowing the player a lot of control over the ultimate level of detail dislayed. There will be many LOD-based implementations throughout the game (such as item descriptions or combat text), but one of the most important to have is also one of the simplest to implement: a zoom control for the tactical map.
