I've been wanting to try this for a very long time. Finally got around to it and bought the game along with all expansions for a really good price at the Exhibition. It's a lovely Co-Op, and I'm down with Co-Ops so this ranks highly in my collection.
Components are of stupendous quality and I was blown away by how simple mechanics could actually simulate true Fire / Thermodynamics.
Also I played it with my brother (who is a Fire Engineer) and he approved and bought a copy as well! :-)
