I have heard SO MANY good things about it! I know a bit about how it plays out, but my husband doesn't, so it's fun watching things unfold for him (when I can get him to stop fishing, that is!). The atmosphere alone is so compelling I just want to sit there and take it all in.
I have so much respect for gaming as a storytelling medium and I want to help support people who are doing new and interesting things with it. So while I don't play very much, I buy games now and again and make my husband play them! He doesn't seem to mind.
