Out of all the minigame distractions I've enjoyed over the years, my favorite would have to be Triple Triad in Final Fantasy VIII. It's a fun card game that was great for a distraction from the RPG grind and actually had an impact in gameplay. Its simple and addictive nature proved to be so popular that several fans created downloadable versions of the game. While it's no as exhilarating as going on a hot card-counting run at Binion's Horseshoe, it doesn't require a bankroll and you won't lose money on a bad run.
