Marsden is Here

This is what I know got played throughout the weekend. You might find whatever you've forgotten.

Unless I'm mistaken the game you picked up from the prize table is Star Realms. Which is a little more involved than DC or Dominion I think, but I expect you'll pick it up without issue. Three currencies if you look at it one way, you win by defeating your opponent instead of reaching some sort of point total or depleting cards. Should you want to be taught instead of teaching yourself I can do so next session we're both at. (It also has a free-to-play starter on Steam if you'd like to learn that way.)
