I just released D6 Danger System last week. It is a fast-paced, rules-light system designed for any setting. All the mechanics are based around a streamlined, player-centered roll so it keeps you in the action and the story. Included in the book is a randomizer for adventure ideas and the system works great for pick up and play games, bringing new people into roleplaying, and one shots especially. It is currently pay what you want at https://criticalmist.itch.io, and I'd love any feedback if you check it out. Thanks!
