I should have known better than to be surprised by this, but I'm expecting to be disappointed after this rolls out. I believe they mentioned already that there would be a Triple Triad-like card game in the upcoming Gold Saucer area, which was exciting news. But, while this app seems harmless enough on its own, I am expecting a lot of heavy cross-promotion and microtransactions. If it's not directly in FFXIV's cash shop, it will be purchases made through this app, or you'll get exclusive cards for the game by pre-ordering this or that.
