If you've got an interest in Margaret Weis Production's Marvel Heroic Roleplaying Game but haven't yet taken the plunge, either to buy the books or get this game on the table, then I encourage you to check out the brand new podcast, "The Doom Pool," to be found right here.
They just released their second episode, and so far Jason, Bryan, and Daryl have done a good discussion of the doom pool mechanic (1st episode) and the effect die (2nd episode), as well as giving several of the published hero files a pretty in-depth review, both how they work and don't work (and Sentry gets what is, in my opinion, a much-deserved bashing almost across the board). They've got an actual play segment at the end of each show, but sadly there's some audio issues that makes it very difficult to hear everyone, particular Bryan/Spider-Man (which is especially unfortunate as it sounds like Bryan was really getting into character) and Susan/Beast. However, that portion is prefaced with Jason discussing where he made mistakes as the GM/Watcher, and why he made some of the rules calls that they did.
They've also got their own sub-forum on the D20 Radio Network (which isn't quite as d20 dominated as used to be), located over here.
Seriously, give these guys a listen. They're informative and entertaining.
