I only have 1 game: Trivial Pursuit, or well, any sort of Trivia game. I will win, there's no question, it just is. years ago, when I worked at a call centre doing overnights, we used to play Trivial Pursuit as there were only 6 of us and we only had about 5 calls a night. I was banned from playing with them by the supervisor.
On the postive side, I'm a hit at pub trivia nights and get myself some free eats (and drinks) wherever I go around the world via pub trivia. :)
