i always wished that in XI there could be an in game Tetra Master trading card game. i always loved the game in IX, and played it for several years in the POL version. so it'd be amazing to have places in XIV where you could buy packs of cards and such and then play it in a guild hall or something. maybe have a point system from winning that lets you buy more cards, and maybe let you spend points on random pieces of gear (more-so cool looking gear than useful gear).

kinda going off the idea of golden saucer type thing (which i'd also love) but just an idea
