Neon Twilight pairs a rules-light and somewhat standard role-playing game with a rich, textured, and well-developed Cyberpunk setting focused on North America in 2037. Published in 1999, many of the "future events" noted in the game's timeline are remarkable prescient while others are familiar tropes in cyberpunk. The site provides these major HTML sections, each with sub-sections: Main, World, Timeline, Society, Entities, Mutation, Gameplay, Techno, Missions, Fiction, and Misc.
The online product is complete and usable, though the author notes only about half of the completed material is available through the site. Much additional material is freely available from the author upon request.
