honestly, to all those who want to sell cards for gold; there quickly comes a point in the game where gold is just nearly useless, except for buying Material+ packs when they arrive at the store, but you'll have more than enough gold for it when it comes.
wow the audio on this game. "Are you my precious?" by that ghoul sounds like a preschool child doing his scary voice Golum impression. this is horrible.
gold is really no issue in the game, you quickly start earning enough that it would be a shame selling cards for it. cards can at least be used to craft stuff.
