Despite the fact that I have neither room nor house (I'm working towards it T^T ) , I thought I'd drop a suggestion for two new furniture items that might be interesting for you.
Basically, a shogi and/or go board/set.
I'm a go player myself and would enjoy seeing these in the game, though I know in game triple triad is said to be the game of choice across eorzea.
But a Miqo'te can dream right?
(Also, hope I posted this in kinda the right forum location?)
