Chronicle Prologue
The History of Promisance
From a PHP BBS game to an iOS throne hall — a chronicle of the empire game that refused to die.
Promisance began life in the early 2000s as a browser-based, text-driven empire game — one of the founding entries in a genre that today goes by names like "4X" idle and "economy MMO." Players managed land, peasants, grain, gold, and military units through screens of pure numbers. Combat was a calculation. Diplomacy was a forum thread. It was the strategy game for people who liked spreadsheets more than graphics.
It should not have survived. The web moved on. Flash died. Ruby and Rails came and went. React ate the world. And yet — twenty-odd years later, Promisance servers still run. Clones still boot up. Forks still fork. A small, stubborn community still logs in every few hours to spend their accumulated turns and scheme against old rivals.
I. Origins
Promisance descends from a family of late-90s games that played a decisive role in the birth of browser strategy: Earth: 2025, Kings of Chaos, and further back, the PBM (play-by-mail) wargames of the 1970s and 80s. It borrowed their essential move — a persistent world, asynchronous play, turns accrued over real time — and stripped it down to pure economy and war.
The original Promisance code was written in PHP, open-sourced, and subsequently forked more times than anyone has bothered to count. Every fork adjusted a few numbers. Some rebalanced the market. Some added magic. A few added graphics, most did not. The source tree became a geological record of two decades of browser-game design: what worked, what didn't, what people kept coming back to.
II. The PHP Era
Through the 2000s and into the 2010s, Promisance communities lived on shared hosting, cheap VPSes, and the benevolence of hobbyist admins. Rounds ran for weeks. Players knew each other by empire name. Clans formed, feuded, fractured. Cheating wars erupted; moderators resolved them with database queries. Nothing about the experience was polished. Everything about it was memorable.
What Promisance did exceptionally well — and what almost no modern mobile strategy game does well — was make every action feel consequential in slow motion. You didn't see an animation when you attacked. You saw a number change. But you had been thinking about that attack for six hours, and the player on the other end had been preparing a counterattack for three. Tension lived in the wait.
III. Forks and Clones
The wider genre that Promisance helped shape — browser empire sims — splintered in a hundred directions. Some clones went graphical. Some went competitive. Some went pay-to-win and were rightly ignored. But the family tree kept branching. In the mobile era, the mechanics migrated onto phones, usually badly: free-to-play hooks swallowed the economy, and the games that emerged were shiny, profitable, and hollow.
Through it all, Promisance itself kept running. New forks appeared in 2018, 2021, 2024. People who had played the game as teenagers came back as adults to play with their kids. The game was, and remains, a remarkable example of a piece of software that refused to die because the thing it did — slow strategy played against people you started to know — still has no dominant modern equivalent.
IV. Ruinkeep Today
Ruinkeep is a spiritual successor to Promisance, built for iOS from the ground up. It keeps the core move — month-long rounds, turn-based economy, market manipulation, military, magic — and layers on the things a modern game can do: push notifications when a rival attacks, in-app direct messages, clans with chat, a Herald feed that broadcasts the realm's drama.
It isn't the original. It doesn't want to be. The original's PHP source will keep running on someone's VPS forever, and good. Ruinkeep is the game for anyone who looks at a modern mobile strategy title and thinks: there should be something slower, sharper, and meaner than this. With numbers. And with people.
