What do Crysta cost in $ USD?
What does game time cost in Crysta?

(Sorry if this has been answered repeatedly. I did try searching for it, but just found lots of marginally related conversations that didn't get down to actual numbers.)

Also, is there a good description somewhere of how this works? (Where to go for each of those transactions, whether the Mog Station is still Windows only or for everyone, etc... I've seen some mentions in other discussions, but usually some prior knowledge was assumed, so the discussions were a bit confusing.)
