Triple Triad is still far and away my favorite minigame in *any* game I've ever played.

Also you know what's broken? Chocobo World is. On the PC version, it literally removes all limits on your power as soon as you get access to it. Thanks to a glitch you can eternally deliver items from it without losing them on the Chocobo World side, allowing you to get infinite stat ups, potions, well just about anything really. And you can let that game run by itself automatically if you know how.
