National Lampoon's Chess Maniac 5 Billion and 1

National Lampoon’s Chess Maniac 5 Billion and 1 is a quirky DOS chess video game released in 1993 by Spectrum Holobyte with humor branding from National Lampoon. It parodies traditional titles like Chessmaster and Battle Chess, blending standard chess play with irreverent animations, sarcastic taunts, and chaotic cutscenes whenever pieces capture one another. The computer opponent may mock, distract, or even “cheat,” making for an unpredictable experience that’s more comedic novelty than serious strategy.
