oh come on community reps please, please, pretty please find out for us.
most of us who used Ultimate Game Cards want square enix crysta cards or some other suitable alternative.

I got a email from Ultimate Game Card|Ultimate Insider suggesting Rixty and OpenBucks. which I suspect both would be suitable.

I have a feeling Playspan/UltimatePay would be happy to oblige SE on SE Crysta Cards. putting FFXI and FFXIV on the cards themselves would guarantee they got noticed as well
