Updating Triple Triad

[Enkidoh]

I still think they should have gone with Tetra Master instead of Triple Triad

Except they already did that with FFXI (okay so Tetra Master was not actually built into FFXI but simply bundled with FFXI/PlayOnline Viewer as a separate game with an independent subscription), and as it was not very popular with players sadly (the separate sub was a sticking point, and only really saw a flurry of activity when FFXI was down for server maintenance, I thought it was fun though and a nice change of pace from when FFXI annoyed me too much), little wonder they went with FFVIII's Triple Triad this time around.

What about updating TT to be able to fit bigger boards and bigger decks?

The existing board size is actually how the game was originally designed in FFVIII, it's a fundamental aspect of it (the only thing SE really changed for it here in FFXIV was that you thankfully don't lose 'flipped' cards if you lose a match, and they toned down the stupid regional play rules that were forever the bane of many a TT player's existence in FFVIII, instead allowing rules to be agreed upon between players or having rules differ between NPC challengers). Hence I don't see SE changing it at all.
