Yu-Gi-Oh!'s anime almost exclusively focused on Duel Monsters, but that game's first spinoff could have represented a perfect chance for the series to change direction and return to its roots. Of course, it never took this opportunity and instead focused on the much more profitable exploration of the trading card game, but it is interesting to imagine what the series would have been like if it had also embraced this new activity. It certainly would have given more credence to Yugi's famous "King of Games" title.
