My lunchtime hiking buddy and I thought that the noble defense of our beloved San Gabriel Mountains against fires would make a great, and instructional video game. Some of our thoughts:
Behaviour of the fire relative to local fuel, terrain, climatic conditions, local and self-generated weather.
Realistic characterization of the range and its topology.
Specific difficulties, problem vegetation (do you lose a point, or get a bonus for yucca-stabs?).
Interaction with the forest critters (bears, snakes venomous and not, deer, mountain lions)
Interaction with human inhabitants (recalcitrant hikers

Interaction with fire crews / Hot Shots from other jurisdictions (think Star Wars Cantina scene)
Aircraft, aircraft, aircraft (fixed and rotary wing)
The obligatory press conferences and incident reports (use local on-air talent for "authenticity")
I haven't the time or resources to pursue this and I imagine it might sell a whopping three or four copies due to the constructive and specialized nature of the topic.
Food for thought...
