1993
Although derivative of its genre, Fighter’s History (Data East, 1993) boasted one key innovation – in its final bout, the player faced off against Karnov, the protagonist from Data East’s 1987 platform title of the same name, thus making Karnov the first guest star in any videogame. Capcom was so unimpressed by similarities between Fighter’s History and its own smash-hit Street Fighter that it took legal action against Data East. Ironically, Capcom now produces many combat crossovers filled with guest stars.
