The problem - every one of these is about 75-85% similar to every other one. Because it's industry stuff, it's game site podcasts, everyone is talking about mostly the same games and mostly the same news. At that point, it has to become voice and personality. The reason I like the Bombcast (and Jcass, a year ago, I was in the same boat with you on your Bombcast feelings. But since then, I've visited their site quite often and enjoy the guys and the site much more and find the 'cast far more enjoyable.) is because it's 4 dudes that run the place. Yeah, there's an intern and some web guys, but that's it. So when they're talking, it's the guys from the site, it's the opinions and reviews and personalities that are that site, not just what some company has decided will be the voice for it.
IGN, Joystiq, Totally Rad Show and even, to a lesser extent, Idle Thumbs, RebelFM and Gamers With Jobs are difficult for me to listen to. They haven't risen above the "genericness" of the video game podcast. I don't necessarily agree with Jcass that they should all be like a radio show but they shouldn't all have nerd voice and all talk about the same goddamn things.
The CHUD Show is an excellent example on how a podcast can break the mold. Sure, it's a "movie" podcast, but there is no way in hell it's talking about the same stuff as a weekly "here's what we saw in theaters this weekend" podcast. It's weird and rambly and different and has (as long as Steve shows up) 3 distinct personalities and that is what separates it from your everyday shit.
And everyone should listen to A Life Well Wasted. Hey, look, the
website.
