OOON

OOON is an original fantasy RPG built to bring retro adventure directly to your web browser. Embark on an open-ended journey across a vast continent, tackle perilous contracts, and pass down your legacy to the next generation.

Designed as an homage to the golden era of tabletop and computer roleplaying, OOON combines the high-stakes attribute checks and dice-rolling tension of classic TRPGs (such as Tunnels & Trolls and Warhammer Fantasy Roleplay) with the non-linear, life-sim freedom of classic Japanese CRPGs like Lunatic Dawn.

Key Features:

• Nostalgic Tabletop Spirit: Inspired by classic 1970s tabletop mechanics. Roll 3D6 for your core attributes, select your race and class, and overcome unforgiving, stat-based skill checks in the wilderness.
• Open Sandbox & Questing: Reminiscent of Lunatic Dawn, forge your own path. Accept town contracts, build your local reputation, and travel freely without forced linear storylines.
• Generational Legacy: Time flows with every journey. Build a home, retire when your body grows weary, or pass your accumulated wealth and gear to your successors.
• Tactical Turn-Based Combat: Utilize an original combat system with weapons, armor, and versatile magic to defeat sloughed horrors and rogue veterans.
• Zero Installation: Built with clean HTML/CSS/JS — jump straight into the adventure on desktop or mobile browsers.
