Short and Simple After Effects Fire Tutorial

I'm planning on making a ridiculously over the top video game intro sequence for the title project, and, in my opinion, you can't have a ridiculously over the top anything (or a good one, anyway) without fire and explosions. Simulating such things in After Effects probably requires quite a lot of time and effort, along with one or two additional plugins, but I found a pretty good tutorial for simulating fire using the particle system already built into the app. Of course, the fire simulated through this tutorial isn't as high quality as a much more advanced tutorial would deliver, but I think the end result is still decent enough to get the point across.
