Currently the FAQ description of this site (which I see is appended to any question that is migrated from this site to another SE site) includes the lines.
This question came from our site for people who like playing board games, designing board games or modifying the rules of existing board games.
Similarly the FAQ contains the lines
Board and Card Games - Stack Exchange is for people who like playing board games, designing board games or modifying the rules of existing board games.
After which the FAQ then goes onto further define what that actually means. On first sight this seems to exclude a number of games which are on topic for boardgames.se. I am thinking particularly about both traditional card and collectable card games which by most peoples definition would not be defined as a board game. Is it possible to make these lines in the site strap line and FAQ reflect this site better and demonstrate that the site is in fact more inclusive than it currently appears.
