I think Triple Triad, as far as I noticed, got the most feedback as far as the mini-games aspect goes. I agree it should be done after all the fixes are done, but I think it'd be a great addition! I loved the system in Final Fantasy 8, it was simple yet complex at the same time, and I think it'd be awesome to be able to farm cards from monsters. I actually had an idea in how you could receive certain cards.

Kind of like in other games where you get "Titles" for killing a mob a certain amount of times, in FFXIV perhaps you could just receive a certain mob-type's card?

Example:

0/100 [Spriggans]
100/100 [This one type of Coblyn] - You recieve This Coblyn's Card
34/100 [Another type of Coblyn]
12/100 [Peist]
100/100 [Foot-soldiers] - You receive the Footsoldier card.

And for really really difficult monsters, you would have to kill them 10 times instead of 100, but 10 is still enough for it to be difficult to get!

For anyone who doesn't know, this is what Triple Triad was like:

Think for a game like FFXIV, where the Leves look like cards, the devs could certainly get pretty creative with the monster cards you recieve.
