I know I'm late listening to this podcast, but I'd still like to give you kudos on a job well done; you've gotten three great interviews in a row. I never played or even heard of this game before this podcast, but after listening to Barwood speak I'm up for giving it a shot. Think I should emulate it...?
Seriously though, this is the first time I've heard a developer tear into the small cartridge sizes so vociferously, although I'm sure that he's not alone on that. It was interesting to hear how ordering cartridges worked though, and I can only wince at how much worse things must have gotten during the N64 era.
I'm also surprised to hear someone from Lucasarts openly admit that Lucasarts is terrible at marketing anything that isn't Star Wars or Indy: I grew up loving their original Adventure games, but I always suspected that for all the internet love they were never huge sellers, and that individual developers often had to fend for themselves. Was Sierra a bigger player on the market? Also, while I love Grim Fandango and would never want it to be undone, I'm sorry to hear that its failure led to other projects' cancellations.
