Does anyone know of any good ones that are still active?

there's one this guy created available for free download on my site, link below.
really involved.
i sue little bits of it for reference to play a scaled down version

Are we talking Role Playing Games or Rocket-Propelled Grenades, here?

LOL, I suppose I really should have clarified that on a board like this ;) However, I'm looking for an rpg group like the ones that YO JOE links too, but that are still active, as those two seem to be dead.
