I play casual Magic, along with a slew of other board and card games. It seems that every week my board game group and I are trying out something new, so I've had exposure to a variety of systems and types of games. My girlfriend and I also create tournament brackets for the 16 Summoner Wars guilds and play through those. This includes rankings and win/loss records, both for each guild and for her and me. We're nerdy like that.
