I fucking finished Pool of Radiance. 18 episodes of a 1988 AD&D game became The Pools Saga: hand-drawn maps, dice decisions, party wipes, and four assholes I somehow ended up caring about. Start at Episode 1: samthul.com/pages/floppy...

I deeply respect your decision to make QuestLord II *completely* by hand, and so will many others. I think you do amazing work, and I'll always support the arts (that means you!). Happy to assist you in this and all future efforts (in the tried and true ways ;) ).

I would consider it a big loss if you dropped me over exploring AI. I say this because I'm giving an 8-bit AI presentation in November on an agentic harness I made for analyzing binaries to see how the ancient ones did their 8-bit magic back in the 80s, and to preserve that history.

Victimhood culture checklist: - polarizing "us-vs-them" mindset - poor conflict resolution - dependence on validation - resistance to feedback - reduced personal agency (and expecting others to perform agency on their behalf) - loss of credibility over time

I once saw an "it is what it is" t-shirt like this in an online store. I can't find it (which drives my OCD nuts), so I had AI mockup the image (although I have aphantasia, so I'm sure I got the overall style wrong). I'd love to buy it from the original artist if anyone could find it:

How do you kill a Supercomputer?

 (Accidentally) using radioactive solder is a good way.

 IBM’s Blue Gene/L frequently crashed when running simulations at LLNL.

 Turned out that alpha particles from the lead solder in the board carrier were slamming the L1 cache with bit flips.
