I like GS content, but I think they need to keep things simple. Not everything needs to be its own gigantic meta-game, which is one reason I enjoy GATEs. Most of them are over in a span of ~3 minutes, and (aside from Skinchange, I dislike that one because some of the changes are so insignificant that it just becomes annoying to check each and every detail and try to remember...) for the most part they are all fun. Getting good at Verminion and Chocobo Racing takes lots of time and practice.

Same can be said for Triple Triad, but it has the luxury of allowing duties to drop cards and increase the chances of the player. As of yet, Triple Triad is probably the most popular and relevant game Gold Saucer has, despite Heavensward Areas having an overabundance of Random/Roulette rules and infuriatingly low drop rates. I hope that they take some time to rethink this as well.

Ultimately, my main point is that I think the primary lure of GS at this point is the smaller activities that players can do without much focus. Adding more ideas based on this idea would be good to build onto for the future.
