Essay The Funny Bits: What Falls Out When You Finally Read 120,000+ Trivia Questions This whole project is built on a stack of cracked 1980s arcade ROMs and an honest fact: nobody had the time to read all 120,000+ questions before. Now they've been read, and the funny bits, the typos, the sex jokes, the wrong answers, the editorial drift, finally have a witness.
Essay Who Stole From Whom: 1,400+ Plagiarism Hits Across 9 Cabinet Manufacturers After cracking 120,000+ trivia questions out of 1980s arcade ROMs, we ran a cross-cabinet similarity scan. The results read like a courtroom. Exidy and GEI share 221 verbatim questions. Bally Sente, who licensed Trivial Pursuit from Horn Abbot, shares 196 questions with GEI, questions GEI did not license. Status Games turns up everywhere. The bar-trivia industry was running on stolen content.
