How do you handle the monster cup? I initially used an "opaque containter" as suggested in the rules and then switched to a drawstring bag from another game (either Carcassonne or Alhambra). I had some time on my hands today (wife/kids with Nana) and put together a "Little Box of Monsters." I made it out of foam board and pasted Arkham pics on the sides. The tops seals tight and the inside is lined with felt so I can shake 'em up. I posted three pictures of the monster box below (links to photobucket). Is this excessive (evidence of gamer OCD)?
I'm interested to hear/see what other players use for the monster cup.
