Fire Propagation/ Setting things on fire in Games

Well, I remember a system of fire propagation in L4D, Minecraft, Rust, Just Cause, Tomb Raider

I think in Postal 2 you can light things on fire with fuel and matches, and it would even spread if your in a forestation area opposed to the games usual housing setting

Little Inferno is a must try then.

Far Cry 3. Definitely Far Cry 3.

Don't starve has fire worked into the survival aspects of the game. Pretty intricately actually, if you're caught in the dark you'll die very quickly, so starting a forest fire can save your life.. however it could burn you if you get too close, and you risk losing easy access to normal wood... or your entire base X_x depending on how badly it spreads. It's also the only way to get charcoal. And if you've got the reign of giants expansion (or Don't starve together) there's an entire season dedicated to fires making your life miserable (spoiler: it's summer ;p)

Edit: it's not in unreal engine though so... meh might not be something you care to mess with.

Double edit: As far as how the propagation of fire works in don't starve, when flammable items are near open flames they will start to smolder and smoke over time then burst into flames. In summer the smoldering and bursting can happen at random. The player can actively try and stop the fire by dousing smoldering items before they catch fire.

Flame Over is something that might interest you. I don't know how well it plays or simulates a spreading fire.

I remember some old games like Planet Blupi and Sim Safari had some stuff like that, but don't remember if you could set them on fire or they were scripted events.
In Total Annihilation (great RTS, now on Steam too!) you can set trees and grass on fire by shooting at them and watch an entire forest burn.

Thanks!! I'll start with something for now!!
