Nostalgia vs. Lawyers: Fight!
OpenCiv1 – open-source rewrite of Civ1
Fans revive Civilization I — now everyone’s arguing about DOS, law, and throne rooms
TLDR: A fan project, OpenCiv1, rewrites the original Civilization to run on modern computers, and the community is split. Fans debate legality, how to get a legit copy, and whether DOS is really “obsolete,” while nostalgics just want to decorate the throne room and hit “End Turn.”
OpenCiv1, a fan-made rewrite of the 1991 classic Civilization, just hit GitHub, promising the original feel on modern Windows, Mac, and Linux. The twist? The developer says the game’s logic is based on a disassembly of the DOS version—basically, taking the old game apart to understand how it works—and that sent the comments into overdrive. One camp wants receipts and transparency: tigerlily begged for more detail on how the code was translated into readable form. The louder camp? The armchair lawyers. mmastrac warned that this approach could be a legal minefield, calling it likely a derivative work. Meanwhile, indy asked the awkward question: if people need original files, where do you even get a legal copy today since it’s not on Steam or GOG? Nostalgia warriors also charged in. The project’s README calls DOS “obsolete,” and 1313ed01 fired back that DOS gaming is alive and thriving thanks to DOSBox (an emulator that lets old games run on new machines). In the middle of the chaos, jokesters like dvh brought vibes: “Time to pimp up my throne room,” a wink to the game’s iconic feature. Bottom line: it’s equal parts tech archaeology, legal cliffhanger, and meme-fueled history lesson, with fans torn between preservation, pragmatism, and pure retro joy. News updates are promised on the CivFanatics forum.
