SPOnG's wintery Underwater Castle sees the fourth of SPOnG's videogame podcasts with the regular crew, some sparkling shiraz, lager, pretzels and much video game talk.Mark bemoans that fact that comics (and graphic novels) rarely if ever cross-over to or from video games. Tim and Mat take issue with Steve Jobs over Garage Band. Everybody plays Mod Nation Racers. Svend reports back from several big game events in London (AvP, MAG and another one). We interview John Dennis from Team 17 about Alien Breed, Natal, Worms, iPad gaming and other things. We'd love to hear from you, so post your comments at here or follow us on Twitter @SPOnGDotCom or Facebook. Remember to read http://spong.com every day for your Blighty-side video game news.
