In RNJesus They Trust: Game Design, Your Time & Your Luck is a witty, sharp-eyed exploration of randomness in modern gaming — and how it blesses, tests, or exploits the players who kneel before it. From the ecstatic thrill of a rare drop to the soul-crushing grind of gacha pulls, game developers have turned RNG (random number generation) into a design pillar that fuels excitement and monetization. But where does randomness stop being fun and start wasting your time — or draining your wallet? This book unpacks that question across genres: MMOs, gacha games, roguelikes, shooters, and strategy titles. It blends game design insight with psychological analysis and a dash of sacred satire, portraying "RNJesus" as the unpredictable deity we've all prayed to at 2 AM. Whether you're a game designer, critic, or lifelong gamer tired of losing to the dice, this book offers clarity, laughter, and empowerment. Learn to recognize fair design, spot exploitative patterns, and advocate for gaming systems that respect your time — and your luck.
