Our friend Mr. Frederickson lost his battle with terminal cancer over the weekend. He'd worked for a year to translate the sequel to his favorite Sega Saturn RPG "Mystaria: The Realms of Lore" but passed it to others in his final days. His story:

Unexpectedly had to put my cat Mo' Biscuits down today. He suddenly started having trouble walking over the weekend which then progressed to him no longer eating. He would have turned 20 this year. If you ever stayed the night he likely tried to snuggle with you. I love you Mo.

Who coined "Metroidvania"? It wasn't @jparish.bsky.social, and he'll be the first to tell you. Besides, there are far more interesting questions, like: How did it spread? Evolve? And what's it got to do with rickrolling?

Last month at PRGE, we held a reunion panel with Nintendo employees who launched the NES. Hear from Bruce Lowry, Gail Tilden, and Lance Barr about how the scrappy staff at NOA defied all odds and released one of the most iconic game systems ever: https://www.youtube.com/watch?v=f2WDfsiLiRA

STOP THE PRESSES.
The ROM for the unreleased Famicom RPG Splatter World has been released (in a thread on 4chan, of all places). I've tried it myself, and it does seem to be genuine. If it's a fake, it's a damn good one.
Expect (more) coverage on West Mansion soon.

Agentic AI feels like everyone using a leaf blower at the same time. It saves someone time only by pushing that time & effort to someone else. Customer Support use cases being touted as a great example always seem to fail to ask the people receiving support rather than the business who saved money.
