Glad to hear Jonny that you're still planning on doing a spoiler heavy follow up on Mother 3, as personally I was disappointed with the Retroactive discussion. Someone mentioned during its brief initial discussion on RFN that the game seems to be building to something, and that was the sense I had throughout the majority of the game. This was the big topic I was hoping for discussion on - whether the game makes good on its build up. I feel as Mother 3 is paced more like an old fashioned novel, or a Japanese film than a game, as the plot development starts off slow (aside from the major event in chapter 1 which sets up the whole story) but quickens considerably toward the end. As a result the forum thread ended up becoming primarily a discussion of the divisive ending, and arguably that is what the game relies on as its primary compelling feature (at least this was the sole reason I persevered when I had a tough time with the bosses - my fault for not realising about the frog banks...). I haven't played it, but to me Mother 3 was just like Johnny described Heavy Rain, where there is a combination of hope and expectation that the conclusion to the plot will prove satisfying that motivates playing through to the end.
Also more on the topic of this episode specifically, when the last email from Steve was read I mistook the meaning of it, and at first I thought it had been misunderstood by the crew and was planning on writing that here, but listening back it was me who misinterpreted it. Still I think my mistake could be a potentially interesting question in its own right, even if it is somewhat similar, so I'll be emailing that soon.
Oh yes and just to add to the growing string of approving comments, the stinger to this episode was absolutely hilarious, loved it!
