@anthracite @zebratron2084 That's perfectly understandable, and I wouldn't want you to steal energy from current projects just to revisit something that you'd finished. I was thinking more along the lines of one-off 'booster' cards, rather than entire packs, promoting other works in your catalogue - like Rita, or a Parallax card with the Captains in the traditional Spy vs. Spy positions at each others' throats/freeing each others' bindings, or Drowning City (n of Cups - Cups Overflow?).
@anthracite @zebratron2084 But! New stuff beats bookmarks by far. It's a Parallax, I dig. n.n
