I've had a lot of combustive incidents in my Sims games, whether it's been the invention table setting one of my sims on fire, or chilis setting the whole kitchen on fire or meteors setting the whole property on fire. Lots of fun.
At one point in our (@Featherbelle's and mine) life, we were living out of a motel (it was all we could afford at the time). Some other tenant in the building went to sleep with the oven going. Next thing you know...their suite was ablaze. All of us were able to get out, thank goodness, but the potential was there for all of us to go up in flames.
