We’ve discussed changing what games we play and how we play them but alas we still play games and then let them set gathering dust effectively playing them for the first time every single time we play them. Aaron brings up some good discussion points in his post on Doubling Up over at BoardGameNews.com.
For many people, there are so many games available that playing the same game twice in an evening often feels like cheating yourself of opportunities.
I can really relate to this point. I only get one dedicated game night a month (sometimes I throw in an impromptu night) and it psychologically feels better to say I played two games on game night than it does to say I played one game twice.
