@jparish.bsky.social’s NES (and adjacent) Works series is the most incredible catalogue of gaming history out there, and the new TurboGrafx Works episodes take things to even greater heights imo. He does such a good job contextualizing this weird and incredible system’s American run. Check it out!

Really enjoyed joining this podcast to talk about my time at TJHSST, its impact on my career (largely getting comfortable with everyone being smarter than I!), and how we came for the sports. Hope to see everyone at the TJ 40th!
