I've listened to several of the episodes, and I want to like it a lot more than I do. It sounds to me like the host *REALLY* wishes that he was about 10 years older so that he would have lived through the stuff that he talks about. The show needs someone older to sit in as a co-host. As it is, they just sound like 20-something hipsters who try too hard to make themselves sound legit. I remember the host, in an early episode, saying that he "totally remembers the SNES launch" because when he was FIVE YEARS OLD his mom took him to the mall where they had some set up. Based on a lot of stuff that he's said both on the show, and on the Neo-Geo forums that he was frequenting before he was run off, it sounds like he just recently got into retrogaming and is just buying shit up on eBay as fast as he can.
I haven't listened in a long time, but in the early episodes there were three dudes. The host I don't care much for, and then there's some snarky hipster dude that I also didn't like, but the third guy had a pretty thick southern twang to his voice. That guy I liked a lot. He should have his own show.
Bottom line: What makes these shows enjoyable for me are hosts with knowledge, experience, and a passion for old games. That's what makes Game Sack so great. They lived through that shit, and seemingly never quit playing the old stuff, while also getting into the new stuff. So they have a vast knowledge that comes from years of experience. You can't buy that on eBay.
