Can we have Koi-Koi?

After playing Mahjong for a while,i was wondering if we could have Koi-Koi or even some Poker added into the game.
I can't get enough of the namazu tiles in that game,and I really wonder how good a FFXIV themed hanafuda deck would look! :D
Though,it would make sense that won't be possible if the game's rating gets up because of it. Still worth a shot though!

I was thinking about that. Feels like poker or blackjack would probably resonate better with the international audience in particular.

Of course, I realize Mahjong was mostly added because there are those on the FFXIV team that built it on their free time, and it was only fleshed out and added to the game after the fact. Regardless, I appreciate the Gold Saucer receives regular updates, so hopefully something like your suggestion or these might show up someday.
