If you’re a nerd of a certain age, I apologise – that headline has probably caused you to rupture something in the wizened meat of your lower back, or the swampy catacombs of your cerebellum. If you aren’t, let me explain: Zachtronics are or were a US-based video game developer founded in 2000 by Zach Barth, who put the studio on ice in 2022 and now works at Coincidence Games, a “flexible business framework” involving many former Zachtronics devs. Zachtronics have thrown together all kinds of things – Infiniminer, a block-builder from 2009, is probably the single greatest individual influence on Minecraft, while Eliza is a tremendous visual novel about AI chatbots and labour politics. But if there’s a type of game they’re known for, it’s engineering puzzles and factory games.
