I don't remember the dates or the specific computer so much as I remember the motions and the patterns.

Even those aren't all there, but yeah, it's probably the same thing.

Your new website is cool! I'm excited you put up the Mafiarchy rules; that was a fun, if super elaborate, game. Has anyone played that since we invented it 2 years ago?

It was played at a New Year's party, iirc.
