Tetra Master was a good minigame for IX, but I would rather have a richer strategy card game this time around, along the lines of Magic, Pokemon, etc. Xenosaga actually had a pretty good card game like this. The kind where you build a full deck of 30-100 cards and put it against other people's decks. Fun stuff.
Of course, there's plenty of room for two strategy card games in FFXIV imo. Especially as easy as it must be to develop for Tetra Master.
Ok, now we're going to get slash fiction of Wint x Kachi somehere... rule 34 and all...
Never confuse your inference as the listener for an implication of the speaker.
Good games are subjective like good food is subjective. You're not going to seriously tell me that there's not a psychological basis for why pizza is great and lutefisk is revolting. The thing about subjectivity is that, as subjects go, humans actually have a great deal in common.
