I very, very much miss the old days of GFW Radio, too.
Here's what I listen to every week:
Player One Podcast - Very funny guys with good chemistry. The best part of the show are the occasional stories from the old days of EGM. The only problem is that they're very narrow in the kinds of games that are played-- don't expect to hear any PC gaming talk.
Giant Bombcast - I think this might be my favorite current podcast. Everyone on the show is really funny, and they all seem to be good friends, which I think is very important to the quality of any podcast. Most importantly, these guys play everything, so they're always talking about something new and interesting.
Retronauts/Active Time Babble - Parish has put out an interesting podcast off-and-on for what's been over three years now, I think. The new show, ATB, shows a lot of promise and is really fun to listen to. Parish sometimes seems down on the shows, but they've always been great.
Rebel FM - I fell out of this show in the Spring, and I think a lot of people on GAF did as well. However, it's really come in to its own now, and the show's a lot of fun to listen to.
Geekbox - This show's fun for me, but I think that you kind of have to be familiar with the personalities before it's really likable.
4Guys1Up - I was skeptical at first, but I think this show is going to be really good. The guests have been great so far, and David Ellis makes a great host.
