Card Game?

[Kirol]

Ok, so... Recently, I spent some time in Germany for Distant Worlds, and during the off-time my friend and I were playing some FF9... and it reminded me just how fun Tetra master was. It came included with FF11 as a separately execution-able game, which I think might be why it got as poor a reception as it did.
How much interest would there be for a Final Fantasy PVP/PVE card game included in XIV?
I know I'd be up for it, and it'd be a hell of a lot more fun than Atma.

I'm talking like... Certain NPCs that you can play cards with, win their cards, and play in a dungeon too. Perhaps in one of those pop-up windows like your inventory screen and whatnot. It doesn't need to be an instanced area in itself - though maybe a card tournament area would be cool. PVP card tournament go! (Maybe?)

You could get cards from mobs as drops, or crafted by DOH, won from NPCs or given from quests. They perhaps could be leveled up through use like FF9's Tetra master or Transformed into items a la FF8, there are a lot of opportunities here.
