I actually like this idea. Along with this I like the video reviews as well, possibly using the same members of the podcast with a 10 minute time slot or so to discuss and rate the game. I would very much listen to this, and possibly even offer my services.
We could all get on the IM feature and answer questions and the like as well! That is if we are doing it live. Or even create a thread and ask the viewers of vgchartz to shoot us questions or what not.
We can have a prediction segment too! Oh look at me I am getting excited our little site is getting so big :3
