Last year, I played with the cards, and got through Rhogobel.
This year, I've been playing using OCTGN rather than the actual cards. This is mostly for convenience, but also lack of a good playing table.
I've just finished Rhosgobel, and am starting Emyn Muil. I hadn't opened the Emyn Muil pack yet, so it was sort of exciting to physically open it, even if I'm going to be playing in OCTGN.
But then I realized that by opening the cards, I'm devaluing them.
So I am wondering: for those of you who play virtually (via OCTGN, LackeyCCG, or VASSAL), do you open your quest packs and expansions? Or do you keep them sealed?
