There's no button to buy power. There never will be. Everything you're carrying, you earned — and everyone can tell. A real MMORPG you can play while the show is on: combat resolves on its own, nothing is timed, and it waits for you when you put it down. You start with a stick. Months later you're selling rare gear on a player-driven market where every price was set by a person, not a shop — and caring far more than you expected to. No ads. No pay-to-win. An optional subscription adds convenience, never power. Built and updated by one developer, with a small community that's kind to new players.
