An open-source browser MMO: nine classes, quests, dungeons, a market.

OUR TAKE The most surprising build: a working MMO, with MMO problems.
Open worldofclaudecraft.com and roll a character — nine classes to choose from.
Quest through the starting zone, then group up for the five-player elite dungeons.
Trade, duel and use the player market; the same world runs on desktop and phone.
Dungeons are tuned for five — soloing one is a reading of the patch notes, not a challenge.
Crafting materials move with the player base; sell into patch days, not weekends.
The code is MIT and the simulation core is also a reinforcement-learning environment — read it if you want to know exactly how combat resolves.
