I'll land a hot one. The gold saucer sucks, it's a mini scale version of everything thats bad about FFXIV.

-Has a bunch of boring, minigames that suck, and aren't fun after a few minutes of playing.
-Rewards are mediocre for the amount of grinding required.
-Leap of faith is either too easy, or too long.
-Triple triad sucks, and isn't fun to play, even against other players.
-Most people aren't even aware of the existence of Doman Mahjong, or Vermillion.
-Chocobo Racing exists.

Similar to XIV where our side content (AKA anything that isn't the MSQ) is half baked, and poorly designed. They drop the ball on everything, and kick it down the road for further expansions to *maybe* pick up again. Lots of potential, the majority of it wasted.
