I require your missives once again! It's mailbag time

Tomorrow, I will hop onto a bus bound for Narita International airport. Then I will commence to travel backward in time to land in San Francisco about eight hours before I left Japan, whereupon I will sleep a lot before powering through a weekend of recording Retronauts episodes with Bob and a motley host of guests. I've already gathered listener correspondences on the topics of Secret of Mana and Breath of the Wild; now I ask your help for one final endeavor. The third of my topics for the coming weekend, I'm afraid, is the most niche of the three (which is by design, you know — Bob and I always try to balance topics that have broad appeal with more esoteric matters every time we record, for diversity). And that topic is...

- drumroll -

...the Dig Dug and Mr. Driller expanded universe. Yes, Namco's classic arcade game somehow blossomed into a multi-series interconnected world that spans decades and appears to have a reasonable amount of continuity. It's probably just a matter of time before someone tries to create a "cinematic universe" out of the properties, but in the meantime, we'd like to discuss the ins and outs of the series.

And yes, we know about Dig Dug's bizarre, Bomberman Act Zero-esque turn in Namco X Capcom.

As usual, please drop me a line with your thoughts on the games at jparish -at- retronauts - dot- com. Please try to keep the word count to around 200 or so! And keep on diggin'.
