When a resource or strategy card is discarded, should it be discarded face up or face down?

I'm pretty sure all discarded cards are face-up. It doesn't specify for the resource cards, but page 13 does mention placing discarded strategy cards "faceup."

Cool. That's how we've been playing it, but I wanted to be sure. Thanks!

I don't think it matters how resource cards are discarded. But strategy cards need to be discarded face up. Knowing which strategy cards have already been played gives you the opportunity to second-guess, or even work out which strategy your opponent is playing. Sometimes this can be very important because it can influence how you play. A good example is knowing when your opponent is playing the Deception strategy.
