conventional wisdom for the entire time i've been programming has always been "less code is better". the idea that we must write more code faster is ridiculous. the problem has never been rate of output

And yes, the CM story gets more complicated. Tweakbod identified this 1978 commercial for a Breakout and Pong-style game table by Bally Japan (which itself is a crazy story as it is NOT affiliated with Bally Mfg). So be careful when you say "first" folks.

Japanese used bookstores are reporting a massive uptick in bulk purchases of used Japanese books by overseas buyers, seemingly without any regard to their contents. The only logical conclusion is that these books are being stripped, scanned, and discarded to train AI models.

without getting into debating the value of numerical scores at all, I have always kind of hated the way Metacritic assumes scores can be easily translated into their preferred scale 2/5 and 40/100 read extremely differently. in a very "$3 is $5 but $2 is free" kind of way

The Gigo #3 in Akihabara continues to be a shining beacon in a sea of cultural despair. They replaced their regular Outrun 2 cabinet with an SP DX and it is a religious experience. Some of the craziest hydraulics I've ever experienced and a legit unhinged 2-player, 1 car co-op. Play it if you can. 🥹

Hey, you can still download games on the PSP. I also noticed Jumping Flash! for the PS4/PS5 was free for me, perhaps because I bought it for the PSP years ago. It's usually $9.99.

Arika's Mihara is Mihara-ing once more: apparently, he was quietly working on a home port of the long-out-of-service Druaga Online arcade game, but now that he's seen people have just got it running via emulation, he's taking his ball & going home (but admittedly might change his mind a la TGM)

speaking of Miyamoto and public acknowledgment of other games, it always tickles me that there will forever remain a cloud over just how familiar he was with certain micom games or whatever but whenever Namco comes up, he gives it up 1000%. true fanboy behaviour

As usual, this is a great thread you should read if you haven't already. One tangent I'll add is that while you may be familiar with some of the board variants of Sega Tetris, including the Master System-based System E, one you'll likely never see in official retellings is this: Taito's own "port."
An arcade PCB of the largely forgotten Taito H System version of Sega Tetris. Aesthetically, aside from the large number of Taito logos spread across various chips, the biggest difference between it and the official Sega PCBs is that it's all contained on one unified board, rather than a main motherboard and a daughter board that houses the actual game data, as is the case with Sega Tetris "proper."

This is the trap that LLMs and other generative AI systems present in this context; if you're generating vast amounts of content from a tiny prompt, what you're doing is supplying your audience with almost nothing and filling in the empty space with the semantic equivalent of sawdust.

The reason why procgen in games is, as we like to say, a great way of getting twice the content with four times the work is that you can't fight Shannon's laws any more than you can fight the laws of thermodynamics. You can't give the audience more information than you were willing to put in.

I genuinely think a lot of people hear this at work genuinely don't realize most custom models are largely built on top of a base model because no one artist or studio has nearly enough data like REMOTELY enough data. You train like a LORA or something you put on top of the base model.
